2 are provided, and massage mechanism covers 13 and 13 are arranged to cover the massage mechanisms 20 and 20, respectively. Although the massage mechanism 20 and the massage mechanism cover 13 have different configurations, they have the same configuration, and therefore only one massage mechanism 20 and the massage mechanism cover 13 will be described below.

A massage opening 13a is formed on an inclined surface of the massage mechanism cover 13 facing the other massage mechanism cover 13, and the pressing member 22 is partially projected from the massage opening 13a. The mechanism 20 is arranged on the support body 11. A cloth cover 15 is attached to the inside of the massage opening 13a so as to cover the pressing member 22 provided with the pressing protrusion 21.

Next, the massage mechanism 20 will be described with reference to FIGS. 4 to 6. The massage mechanism 20 includes a base portion 27 and a rotation drive portion 30 swingably arranged on the base portion 27. The base part 27 is formed in a "U" shape having an upper opening by extending left and right upwards and forming side plates 27a and 27a. The side plates 27a and 27a in the opening have a rotary drive unit which will be described in detail later. Boss (cam member) 3 for swinging and reciprocating operation of 30
A cam receiver 39 that is in abutting contact with 4 is attached.

The rotation driving unit 30 is a rotation driving motor 3
1, a holding frame 32, a motor holding member 33, a boss 34, and a crank member 35. The holding frame 32 is also formed in a substantially "U" shape having an upper opening, and a motor holding member 33 is attached to the opening. The holding frame side swing shaft support members 36, 36 are attached to the lower surface of the holding frame 32, and the base portion side swing shaft support member 28 is attached to the upper surface of the bottom surface of the base portion 27. There is. Through holes through which the rocking shaft 23 can freely pass are formed in the rocking shaft support members 28 and 36, and the rocking shaft 23 is inserted through the through holes to form a base portion. The holding frame 32 is pivotally supported with respect to 27.

A rotation driving motor 31 is attached to the motor holding member 33, and a rotary shaft 31a is attached through a through hole 33a formed in the central portion of the motor holding member 33. The rotation driving motor 31 includes an electric motor 31c and a reduction gear head 31b provided with a rotation shaft 31a.
c is configured so that the rotation speed can be adjusted by the controller 40, the details of which will be described later. As a result, the rotation shaft 31a can be rotationally driven at a rotation speed and a rotation torque suitable for massage.

A columnar boss 34 is attached to the rotary shaft 31a, and a support shaft 34a is formed on the upper surface of the boss 34 as shown in FIG. Then, on the bottom surface of the boss 34, a rotary shaft insertion hole 34b into which the rotary shaft 31a is inserted is formed around a point P that is eccentric by R2 from the center of the boss 34, and the support shaft 34a is further R1 from the point P. It is formed eccentrically. A support hole 24a into which the support shaft 34a is loosely fitted is formed in the central portion of the pressing member holding member 24, and an upper support shaft 35a formed above the crank members 35, 35 also in front of and behind the support hole 24a. , The support holes 24b, 2 in which 35a is loosely fitted
4b is formed. A lower support shaft 35b which is loosely fitted in a support hole 33d of the motor holding member 33 is formed in the lower center of the crank member 35, and the upper support shaft 35a is formed eccentric by R1 with respect to the lower support shaft 35b. Has been done.

The outer shape of the boss 34 is circular as shown in FIG. 8 and is a so-called disc cam.
When the rotation driving motor 31 is rotated as described above, the boss 34 rotates about the point P (center of the rotation shaft insertion hole 34b) as a rotation center. Here, the outer periphery of the boss 34 is configured such that the contact surface 39a of the cam receiver 39 is in abutting contact. The contact surface 39a is an inner peripheral surface in the longitudinal direction of a substantially rectangular hollow hole 39b formed so as to extend in the longitudinal direction with a width that allows the boss 34 to be inserted near the center of the plate-shaped cam receiver 39. . And this contact surface 39a
Is formed in a vertically arcuate shape protruding in the vicinity of the intermediate portion, and is configured to abut and contact the boss 34 at this apex.

The boss 34 and the cam receiver 39 are made of plastic having a low friction coefficient and being hard to wear (for example, polyacetal resin such as "Delrin" manufactured by DuPont Japan Limited). This allows the boss 34 to rotate smoothly while being in contact with the cam receiver 39. Then, as described above, the boss 34
Since the rotation driving unit 30 provided with is swingable with respect to the base unit 27 to which the cam receiver 39 is attached, when the boss 34 rotates, the rotation driving unit 30 swings as shown by an arrow A. I do. That is, as shown by the one-dot chain line and the two-dot chain line in FIG. 8, when viewed centering on the boss 34, the cam receiver 39 makes a swinging reciprocating motion to one side by a movement amount of R2 each.

Further, when the rotation driving motor 31 is rotationally driven, the pressing member holding member 24 makes a circular motion with a radius R1. Therefore, each pressing member 22 mounted on the upper portion of the pressing member holding member 24. Also do circular movements. When the rotary motion motor 31 is rotationally driven, the support shaft 34a
Performs a circular movement having a radius R1 to the rotary shaft insertion hole 34b. As a result, the circular motions of the support shaft 34a and the upper support shaft 35a and the swing reciprocating motion are combined, and the pressing member 21 performs an elliptic motion.

The pressing member 2 will now be described with reference to FIG.
Support shaft 34 in the boss 34 for performing the elliptic motion of 1
The motion trajectory of a will be described. Outer peripheral surface 34 of boss 34
c is the contact surface 3 formed on the cam receiver 39 as described above.
9a, and when the boss 34 is rotated counterclockwise about the rotation shaft insertion hole 34b as shown by arrow I, the outer peripheral surface 34c rotates while contacting the contact surface 39a of the cam receiver 39. The support shaft 34a and the rotary shaft insertion hole 34b move downward in the hollow hole 39b of the cam receiver 39 as shown by an arrow II.

Here, at the position rotated by 90 ° as shown in (B), the support shaft 34a has the rotation shaft insertion hole 34.
While drawing a circle centered on b and having a radius of R1, move downward by R2. Therefore, when the boss 34 is further rotated counterclockwise as shown in (C) and (D), the support shaft 34
In a, the ellipse of the locus a with R1 as the short radius and R1 + R2 as the long radius will be drawn.

As a result, the pressing member holding member 24 makes an elliptical motion, and the pressing member 22 attached to the pressing member holding member 24 also makes an elliptic motion.
The short radius can be changed by changing the distance R1 from the point P to the center of the support shaft 34a.
The major radius can be changed by changing the distance R2 from the center of the boss 34 to the point P. Therefore, the support shaft 34a and the upper support shaft 35a are configured to be detachable, and a plurality of upper support shaft insertion holes having different distances from the point P are formed in the boss 34 and the crank member 35 in advance to change R1. Therefore, the radius of the circular motion of each pressing member 21 (the short radius of the elliptic motion) can be varied. Further, since the stroke of the swing reciprocating motion (long radius of the elliptic motion) can be changed by changing R2, a plurality of rotary shaft insertion holes 34b in which the distance from the center of the boss 34 to the point P is different in advance. May be formed.

Further, in the above embodiment, the boss 3
Although the case where the outer shape of 4 is a column shape (the cam member is a disk cam) has been described, the trajectory of the elliptic movement of the pressing member 22 can be changed by changing the outer shape of the boss 34.

The pressing projection 21 and the pressing member 22 are made of a plastic having a low friction coefficient and being hard to wear like the boss 34 and the like. As shown in FIG. 10, the pressing member 22 is a body part (neck N) where a massage is performed.
It is formed in a concave shape corresponding to the shape of, and pressing projections 21, 21, 21 are formed on the concave surface. Pressing protrusion 21
Is formed in a substantially hemispherical shape (a shape in which a part of a sphere is cut off),
The pressing member 22 is provided at three locations on the center and both sides thereof. The pressing protrusion 21 includes the pressing portion 21 a and the support column 21.
By being inserted into a holding hole 22b formed in the upper surface of the pressing member 22, the support column 21b is detachably held by the pressing member 22.

Then, the pressing member 22 holding the pressing protrusion 21 is attached to the pressing member holding member 24. For this attachment, the engaging groove 22c formed on the lower surface of the pressing member 22 is engaged with the attaching portion 24c formed on the upper portion of the pressing member holding member 24, and the attaching screw 23 is formed on the side surface of the pressing member 22. Mounting portion 24c through the through hole 22a
It is performed by screwing it into the screw hole 24d formed on the side surface of the.

Here, the shape of the pressing portion 21a of the pressing protrusion 21 is not limited to the above-described substantially hemispherical shape, and for example, each corner is R-processed as shown in FIG. 11 (A). Starting from the pressing portion 211 formed in the rectangular parallelepiped, (B)
A pressing portion 212 having a plurality of circular protrusions, as shown in FIG.
One or more elliptical pressing portions 213 shown in (C) and hemispherical pressing portions 214 shown in (D) may be attached.

Further, the shape of the pressing member is not limited to holding a plurality of pressing protrusions as described above, but the pressing protrusion and the pressing member may be integrally formed. Also in this case, the shape of the pressing member is not limited to the concave shape having the protrusion as described above, and for example, the pressing member formed into a rectangular parallelepiped by rounding each corner as shown in FIG. 221, and a pressing member 222 having a plurality of circular protrusions as shown in (B), and an elliptical pressing member 22 as shown in (C).
Alternatively, a spherical pressing member 224 as shown in FIG. Further, as shown in FIG. 13 (A), the upper surface of the rectangular parallelepiped is formed in a semi-cylindrical shape (so-called "kamaboko shape").
The pressing member 225 may be the pressing member 225, or the pressing member 226 may have a plurality of columnar protrusions 226b formed on the upper surface of the substrate 226a as shown in FIG. Incidentally, this protrusion 226b
Need not necessarily be formed radially with respect to the substrate, and may project at different angles.

By constructing the pressing protrusion 21 and the pressing member 22 as described above, the pressing protrusion or the pressing member can be replaced depending on the part to be massaged and the symptom. This allows you to massage multiple points at the same time, such as when you massage with multiple fingertips, or a wide range like when you massage with the belly of your thumb. An effective massage can be performed when massaged.

As described above, the tip of the pressing member 22 projects upward from the massage opening 13a, and when the pressing member 22 makes an elliptical motion in this way, it is placed on the recess 12 of the support body 11. A predetermined portion of the neck portion N of the person M receives the massage by the elliptic movement of the pressing member 22 via the cover 15. At this time, since the pressing projection 21 and the pressing member 22 are formed of the plastic having a low friction coefficient as described above, even when the weight of the person M is added to the pressing member 22, the inside of the cover 15 is prevented. The elliptical movement can be performed smoothly.

Electric motor 3 for performing the above massage
The drive of 1c is controlled by the controller 40 using the electric power input by inserting the plug 51 at the tip of the electric wire 52 into an outlet. As shown in FIG. 14, the controller 40 is a so-called remote control device configured separately from the support body 11, and the support body 11 and the controller 40 are connected to the electric wire 52 or the electric motor 31c by an operation wire 49. . The controller 40 includes a main switch 41, an operation display lamp 42, a left massage mechanism adjusting unit 140, and a right massage mechanism adjusting unit 240. The main switch 41 is a switch for switching on / off of the power source, and when this is turned on, the operation indicator lamp 42 lights up. Further, since the left and right massage mechanism adjusting units 140 and 240 have the same configuration, the left massage mechanism adjusting unit 140 will be described below as an example.

The left massage mechanism adjusting portion 140 is provided with rotation direction switching buttons 143a and 143b and a rotation speed adjusting knob 145. Rotation direction switching button 143a,
143b is a button for switching the rotation direction of the electric motor 31c, and when the counterclockwise rotation button 143a is pressed, the pressing member 2 is pressed.
2 performs an elliptical motion counterclockwise, and a button 143b for right rotation.
When is pressed, the pressing member 2 can perform an elliptic motion in the clockwise direction. The rotation speed adjusting knob 145 is a knob for adjusting the rotation speed of the electric motor 31c. As the rotation amount to the right increases, the rotation speed of the electric motor 31c increases and the speed of the elliptic movement of the pressing member 22 also increases. It should be noted that the right massage mechanism adjusting unit 240 is denoted by the reference numeral with 100 added, and description thereof will be omitted.

The controller for driving the massage device 10 does not have to be limited to the controller having the above-mentioned configuration, and the rotation direction switching button and the rotation speed adjusting knob are not always necessary. In addition to the buttons having the above functions, switching buttons for continuously operating or intermittently operating each massage mechanism, and operating the left and right massage mechanisms at different timings when starting operation A switch or the like may be provided so as to perform (for example, the right massage mechanism has a horizontally long ellipse and the left massage mechanism has a vertically long ellipse).

As described above, the massage mechanism 20, which is independently configured to freely move in an elliptical manner, is swingably arranged with respect to the support body 11. As shown in FIG. 3, this swing operation is performed by the base 16 mounted on the support body 11.
And the rocking column 17. A base 27 is pivotally supported by a massage mechanism pivot pin 18 near the intermediate position of the base 16. Also, the base 16
On the rear side (in the direction of the left and right ends of the support body 11), a swing support 17 is swingably supported by a support pivot pin 16a. Further, a positioning screw 19 is attached to the rear of the base portion 27 (toward the left and right end portions of the massage device 10). This positioning screw 19 is used for the swing support 1
The inside of the long hole 17a formed in the upper part of 7 is slidable,
By tightening, the swing support 17 is sandwiched between the base 27 and the positioning screw 19, so that the support 17 can be fixed at any position.

For example, FIG. 3 shows the case where the positioning screw 19 is fixed near the upper part of the long hole 17a, but when fixed at the lower end of the long hole 17a, the entire massage mechanism 20 is raised. However, when fixed at the upper end of the elongated hole 17a, the entire massage mechanism 20 falls down. Therefore, by changing the fixing position of the positioning screw 19 in the elongated hole 17a, the angle of each of the left and right massage mechanisms 20 with respect to the neck portion N can be changed, so that effective massage can be performed.

Further, in the above-mentioned massaging device 10, as shown in FIG. 15, each massaging mechanism 20 is horizontally rotatable in a horizontal plane, and is also movable left and right. Elongated holes 14a, 14b, 14c, 14 extending in the front-rear (longitudinal) direction are formed on the upper surface of the support body 11 at the positions where the massage mechanisms are arranged.
d is formed at each of four locations, for a total of eight locations. The base 16 has elongated holes 16b, 16 extending in the left-right (lateral) direction.
c and 16d are formed in three staggered positions. Horizontal positioning screws 12, 12 ... for holding the support body 11 and the base 16 are attached to the intersections of these elongated holes. The base 16 can be fixed at a desired position and angle.

For example, the left base 16 shown in FIG.
In the case where they are respectively turned toward the center in a state where they are turned right around the front of the base 16 as shown by the solid line, the slots 16d and the innermost slot 14 of the support body 11 are
an intersection A with a, an intersection B between the front end of the elongated hole 16b and the left end of the second elongated hole 14b from the inside of the support body 11, and an intersection C with the elongated hole 16c and the third elongated hole 14c from the inside. The horizontal positioning screws 12, 12, 12 are fixed by screwing them together. Thereby, each massage mechanism 20, 2
0 is arranged in an inverted “C” shape on the support body 11, and is positioned to face the portion corresponding to the “pot” of the neck N in a state of being placed on each massage mechanism 20, 20, so that the pressing protrusion 21 Massages the "pot" of the neck N into an almost elliptical shape.

Massage device 1 constructed as described above
According to No. 0, by adjusting the amount of swing up and down of each massage mechanism 20, the part to be massaged can be firmly held, and can be moved to the left and right with respect to the support body 11. Since it is also possible to perform the turning operation of, the fine adjustment of the massage position in a predetermined portion can be performed. Therefore, it is suitable for the symptoms ”
Since the massage of the pot can be performed, the effect of the massage can be improved.

In the above embodiment, the rocking / lowering operation, the horizontal movement and the horizontal turning operation of each massage mechanism 20 are held at each position by sandwiching each member with a positioning screw that slides in each slot. However, the present invention is not limited to this. That is,
A drive member such as a drive motor is provided in each moving part,
The controller 40 may be provided with a position determining switch for controlling the driving of the drive member, and may be configured to perform a swinging / lowering operation, a horizontal movement, and a horizontal turning operation by remote operation from the controller 40.

Further, as a massage device in which the pressing member 22 is inclined with respect to the support body 11, as shown in the top view of FIG. 16, the pressing member 22 is inclined with respect to the rotary drive unit 30. It may be configured to do so. That is, in the state in which the rotary drive unit 30 is attached to the base 16 as shown in FIGS. 5 and 15, the pressing member 22 is not attached at a position substantially parallel to the longitudinal direction of the base 16, but as shown in FIG. Alternatively, the massage mechanism may be configured in advance so that the pressing member 22 inclines when the base 16 is horizontally positioned. When the massage mechanism is configured by inclining the pressing member 22 as described above, the massage opening 63a is also provided in the massage mechanism cover 63 in accordance with the inclination of the pressing member 22.

Massage device 1 constructed as described above
According to 0 ', the pressing members 22, 22 are arranged in an inverted "C" shape at substantially the center of the support body 11 in the short side direction. Accordingly, when massaging the neck N, the "vase" can be massaged even if the head is positioned in the direction of arrow II, and the head is positioned in the direction of arrow III (in the direction of arrow II). Even if the massaging device 10 'is turned upside down from the state where the head is positioned, the "vase" can be massaged, and the massage mechanism cover 63 can be used to massage the shoulder of the person who receives the massage in either direction. Etc. will not interfere. Then, by changing the direction of the head, the position and direction of massaging the "pot" of the neck N can be changed, so that the massage according to the symptom can be more effectively performed.

A boss 134 is attached to a rotary shaft 131a of the electric motor 131 for rotary motion. Above the boss 134, a support shaft 134a is eccentrically formed by a radius R1 from the center of the rotary shaft 131a. Are formed. A support hole 124a into which the support shaft 134a is loosely fitted is formed in the central portion of the pressing member holding member 124, and an upper support shaft 135a formed above the crank member 135 is loosened before and after the support hole 124a. The support hole 124b to be fitted is formed, and the cam member 13 is formed.
A support hole 124c is formed in which the upper support shaft 136a formed above 6 is loosely fitted. Crank member 135
A lower support shaft 135b which is loosely fitted in the support hole 133d of the motor holding member 133 is formed in the lower center of the upper support shaft 135a, and the upper support shaft 135a is formed eccentric to the lower support shaft 135b by a radius R1. There is.

The outer shape of the cam member 136 is formed in an oval shape as shown in FIG. 23 (A), which is a so-called plate cam. A lower support shaft 136b that is loosely fitted in the support hole 133b of the motor holding member 133 is also formed in the lower center portion of the cam member 136, and the upper support shaft 136a.
Is also eccentric to the lower support shaft 136b by a radius R1. Then, the lower support shaft 136b is rotated about the center point P of the lower support shaft 136b. This cam member 136
The contact surface 139a of the cam receiver 139 abuts and contacts the outer periphery of the cam receiver 139. The cam receiver holding plate 127a to which the cam receiver 139 is attached and the motor holding member 13
An extension spring 137, which applies an urging force in the contracting direction, is disposed between the extension spring 137 and the position 3. As a result, the cam member 136 is always attracted to the cam receiver 139.

According to the rotary drive section 130 thus constructed, when the rotary drive electric motor 131 is rotationally driven, the pressing member holding member 124 makes a circular motion with a radius R1. 121 also makes a circular motion. Here, the radius of the circular motion of each pressing member 121 is determined by the bosses 134,
It depends on the distances from the centers of the upper support shafts 134a, 135a, 136a formed on the crank member 135 and the cam member 136. That is, as shown by the example of the boss 134 and the crank member 135 in FIG. 22, if the distance from the center P is set to R1 ′ as shown by the alternate long and short dash line, the radius of the circular movement of each pressing member 121 also increases, If the distance from the center P is set as small as R1 ″ as shown by the dotted line, the radius of the circular motion of each pressing member 121 becomes smaller.
Therefore, the upper support shafts 134a, 135a, 136a
Is detachably configured, and a plurality of upper support shaft insertion holes having different distances from the center P are formed in the boss 134, the crank member 135, and the cam member 136 in advance.
The radius of the circular motion of each pressing member 121 (the minor axis of the elliptical motion) can be varied.

As described above, the electric motor 131 for rotary motion is used.
When driven to rotate, the cam member 136 also moves to the lower support shaft 13
Since it rotates about 6b, the rotary drive unit 130 makes a swing reciprocating motion as shown by an arrow A in FIG. 17 about the swing shaft 123 against the pulling force of the tension spring 137. Thereby, the rotation drive unit 13
0 pressing member 121 (upper support shafts 134a, 135
a, 136a) and the swing reciprocating motion are combined, the pressing member 121 performs an elliptic motion. Here, the movement trajectory of the upper support shaft 136a in the cam member 136 for performing the elliptical movement of the pressing member 121 will be described with reference to FIG.

As described above, the cam member 136 is always laid down in the direction indicated by the arrow I in (A) by the urging force of the tension spring 137, and therefore comes into contact with the cam receiver 139. Then, when the cam member 136 is rotated clockwise around the lower support shaft 136b as shown by the arrow II, the outer peripheral surface 136c of the cam member 136 is moved to the cam receiver 139.
The lower support shaft 136b moves to the right with respect to the cam receiver 139 as indicated by an arrow III, because the lower support shaft 136b rotates while contacting the contact surface 139a. Here, in the position rotated by 90 ° as shown in FIG.
“A” moves to the right while drawing a circle centered on the lower support shaft 136b and having a radius R1. Therefore,
When the cam member 136 is further rotated to the right as shown in (C) and (D), the upper support shaft 136a draws an ellipse of a locus a having a minor axis R1.

As a result, the pressing member holding member 124 makes an elliptic motion, and the pressing member 121 attached to the pressing member holding member 124 also makes an elliptic motion. The length of the major radius of the elliptic movement (stroke of the swinging reciprocating movement) can be changed by changing the amount of protrusion of the protrusion 136d of the cam member 136.
Further, the shape of the locus of the upper support shaft 136a can be changed by changing the outer shape of the cam member 136. For example, a substantially elliptical locus can be drawn when an elliptical plate cam or a disc cam 236 formed by eccentricity of the center of the circle and the rotation center P as shown in FIG. .

The pressing member 121 is formed of an elastic material such as rubber or the same plastic as described above in a circular shape and with its corners rounded. This pressing member 121 is
It is mounted on a holding shaft 122 that is held up and down with respect to the pressing member holding member 124. This holding shaft 12
2 is biased upward by a spring 123.
By operating the protrusion amount adjustment buttons 343a and 343b in the controller 140, which will be described in detail later, the holding shaft 122 is moved up and down by the lifting mechanism provided in the pressing member holding member 124.

As described above, the tip portion of the pressing member 121 projects upward from the massage opening 113, and when the pressing member 121 makes an elliptical motion in this way, it is placed on the recess 112 of the support body 111. A predetermined portion of the neck portion N of the person M receives the massage by the elliptic movement of the pressing member 121 via the cover 115. Here, the massage opening 113 is formed at a position facing a portion corresponding to the “pot” of the neck portion N placed on the concave portion 112, and the pressing member 121 massages the “pot” of the neck portion N into a substantially elliptical shape. To do.

In the above embodiment, the holding shaft 12
Although the pressing member 121 on the upper part 2 is formed into a circular shape with rounded corners, the pressing member according to the present invention is not limited to such a shape. For example, as shown in FIG. 26 (A), a pressing member 421 having a plurality of circular protrusions as shown in FIG. One or a plurality of elliptical pressing members 521 shown in (C) and spherical pressing members 621 shown in (D) may be attached.

As a result, it is possible to massage a plurality of points at the same time as in the case of massaging with a plurality of fingertips, or a wide range as in the case of massaging with the belly of the thumb. An effective massage can be performed when massaging the lower back and the like.

Electric motor 1 for performing the above massage
The drive of 31 is controlled by the controller 240 by using the electric power input by inserting the plug 151 at the tip of the electric wire 152 into an outlet. The controller 240 is
As shown in FIG. 25, the support body 111 is a so-called remote control device configured separately from the support body 111.
And the controller 140 uses the operation wire 149 to connect the electric wire 15
2 or the electric motor 131. The controller 240 includes a main switch 241, an operation display lamp 242, a left massage mechanism adjusting section 340, and a right massage mechanism adjusting section 440. The main switch 241 is a switch for switching on / off the power source, and when this is turned on, the operation display lamp 242 is turned on. In addition, the left and right massage mechanism adjustment units 340 and 440
Since they have the same configuration, the left massage mechanism adjusting unit 340 will be described below as an example.

The left massage mechanism adjusting section 340 includes protrusion amount adjusting buttons 343a and 343b and a rotation speed adjusting knob 3.
45 and. Projection amount adjustment buttons 343a, 34
3b is a button for adjusting the vertical movement amount of the holding shaft 122 in the axial direction, and when the up button 343a is pressed, the pressing member 12 is pressed.
When 1 is projected (raised) and the down button 343b is pressed, the pressing member 121 can be retracted (lowered).

The rotation speed adjusting knob 345 is the electric motor 1
It is a knob for adjusting the rotation speed of 31 and changing the rotation direction. When the rotation speed adjusting knob 345 is rotated rightward from the neutral position as shown in FIG. 25, the rotation driving electric motor 131 rotates right, and the rotation speed of the electric motor 131 increases as the rotation amount increases. Then, when rotating from the neutral position to the left, the rotation driving electric motor 131 rotates to the left. It should be noted that the right massage mechanism adjusting unit 440 is denoted by the reference numeral with 100 added, and description thereof is omitted.

Further, the massage mechanism 120 in the massage device 110 has the bottom plate 11 of the support body 111.
It is arranged to be swingable with respect to 1a. As shown in FIG. 16, this swinging operation is performed by the base 116 attached to the bottom plate 111a and the swinging column 117, but since it has the same structure as the swinging mechanism in the massage device 10, 100 is added. The description is omitted by attaching the reference numerals. Further, similarly to the above-described embodiment, the massage mechanisms 12 and 120 may be horizontally rotatable with respect to the bottom plate 111a and may be movable in the left and right directions.

In each of the above embodiments, the present invention has been described by taking a massage device for massaging a person's neck as an example, but each of the massage devices 10 and 110 massages another part of the body, for example, the waist. Of course, it can be configured like this. For example, as shown in FIG. 27, a neck massage device 50 that supports a neck portion N of a person M sitting on a massage chair C and massages this portion.
It is also possible to configure a device in which a waist massage device 55 that supports the waist W and massages this part is attached. In this case, the support body of the waist massage device 55 has a recess that matches the shape of the waist.

In each of the above-described embodiments, the reciprocating movements of the rotary drive units 30 and 130 are controlled by the swing shafts 23 and 12.
Although the swinging reciprocating movement is centered around 3, the present invention is not limited to this, and is movable in the horizontal direction (left and right direction in FIGS. 4 and 19) with respect to the base portions 27, 127. It may be configured. In this case, the pressing members 22 and 121 will make an elliptical motion on the same plane.

Further, in each of the above embodiments, the massage mechanisms 20, 20 or 120, 120 are respectively used as two massaging mechanisms.
Although the massage devices 10 and 110 provided one by one have been described, the present invention is not limited to this, and one or three or more massage mechanisms may be provided and configured.

Further, although one rotation driving electric motor is used as the driving means for making the elliptical movement and a mechanism combining the rotation movement and the reciprocating movement is used, the present invention is not limited to this, and the pressing force is applied. Other mechanism may be used as long as the member can move in an elliptical manner. For example, as shown in FIG. 28 (A), if a so-called elliptical compass (elliptic tramel) mechanism in which sliders 781 and 782 slide in orthogonal grooves 783 and 784, respectively, the arm member 78 is used.
A point A on the extension line of 5 performs an elliptic motion having a locus indicated by a chain line. Therefore, when used in the massage device, the support shaft 34a of the boss 34 or the upper support shaft 36a of the cam member 136 in the above embodiment is set to point A, and the sliders 781 and 782 are slid by the driving electric motors 31 and 131. By moving the pressing member 2
It is possible to make the elliptical motion of 2,121.

Further, as shown in (B), in the so-called crank swing arm and elliptic crank mechanism, by rotating the cranks 791-792 about the point 791, the pin A in the grooved slider 793 is indicated by a chain line. Indicated by a
Performs an elliptic motion with the locus as. Here, as shown in (C), a short link 803 is used instead of the grooved slider 793.
Even if it is configured by -804, the elliptic motion of the point A can be performed by rotating the cranks 801-802. For these mechanisms, the cranks 791-792
And an electric motor 3 for driving the cranks 801-802.
1 and 131, the point A is supported by the support shaft 3
4a or the upper support shaft 136a allows the pressing members 22 and 121 to move in an elliptical manner.

Further, as shown in (D), a Scotch yoke mechanism which rests at both ends may be used. In this mechanism, the spur gear 811 is stationary with a diameter twice that of the spur gear 812. And the crank 813-814
Rotates about a shaft 813, and the shaft 814 of the spur gear 812
Is the crankpin. Here, the pin A protruding from the surface of the spur gear 812 is a pin of the Scotch yoke 815-816.
To form the pins for the slots. As a result, the cranks 813-814 are rotated once by the driving electric motors 31 and 131 to move the point A to the support shaft 34a or the upper support shaft 1a.
If it is set to 36a, an elliptic motion having a locus indicated by an alternate long and short dash line will be performed.

Further, as shown in FIG. 29A, in the elliptic mechanism composed of a fixed internal gear and a gear rotating on the inner circumference of this gear, the fixed internal gear 8
21 is a spur gear 822 having a diameter half that of the internal gear 821.
Are engaged. When the spur gear 822 is rotated while being inscribed, the point A other than the pitch circle of the spur gear 822 is rotated.
Performs an elliptic motion with a as a locus indicated by a chain line. In this case, the rotation center 824 of the cranks 824-825 that rotate while inscribing the spur gear 822 is rotated by the drive electric motors 31 and 131, and the point A is set to the support shaft 34.
By using a or the upper support shaft 136a, the pressing members 22 and 121 can perform an elliptic motion.

Further, as shown in (B), a cam 832 having a desired elliptical cam groove 832a is formed.
In addition, the elliptic mechanism may be configured to perform an elliptic motion by an elliptic mechanism in which a pin A disposed on a slider portion of an arm member connected to the crank 831-834 slides. According to such a mechanism, the crank 831-834 is rotated by the driving electric motor 31 or the like, and the point A is used as the support shaft 34a or the like, so that an elliptical motion with a as a locus can be performed.

Further, as shown in FIG. 30 (A), in the link composed of four arm members, the link 84
1-842 and 845-844 have the same size (I), and links 842-843, 843-844, 842-
A and 844-A may be configured to perform an elliptic motion by an elliptical compass (ellipsograph) mechanism configured to have the same size (II). According to such a mechanism,
When 845 is stopped and 841 is driven on a straight line passing through 845, the point A is a major radius I + I whose locus is a.
It is possible to perform an elliptic motion with I and a short radius I-II. Therefore, the elliptical movement of the pressing member 22 and the like can be performed by using the point A as the support shaft 34a and the like. In this case, since the point 842 also draws an ellipse, this may be set as the point A. Further, the point 842 may be on the extension of the straight lines 841-843.

Further, as shown in (B), a mechanism of a Swadi ellipse drafting machine may be used to perform an elliptic motion with the point A as the locus. In this mechanism, the spur gear 851 is stationary with a diameter twice that of the spur gear 852, and the intermediate gear 853 is a spur gear 851, 8
52, respectively, and is rotatably held by arms 854 and 855. Here, the arm 8 having the point A
Since 56 rotates with the spur gear 852, the spur gear 8
If point 51 is made stationary and the arm is rotated once, point A makes an elliptical motion. The locus a can be changed by changing the angles of the arms 854 and 855. Therefore, the elliptical movement of the pressing member 22 and the like can be performed by using the point A as the support shaft 34a and the like.

It is also possible to use the mechanism of an ellipse drafting machine as shown in (C). This mechanism has bevel gears 861, 862, 863 formed with the same number of teeth and a bevel gear formed with half the number of teeth of these bevel gears. Bevel gears 862, 863 rotate with horizontal axis 865, and bevel gear 861 is stationary. The vertical axis 866 rotates with the bevel gear 864, and a horizontal axis 867 having a point A is provided at the lower end of the vertical axis 866. As a result, when the frame 868 is rotated with respect to the base 869, the point A
Draws an ellipse with I + II as the major radius and I-II as the minor radius. Therefore, by rotating the frame 869 by the driving electric motor 31 and the like, and by making the point A the support shaft 34a and the like, the pressing member 22 and the like can be caused to make an elliptical motion.

In each of the above explanations, the pressing member 2
2, 121, the support shaft 34a, and the upper support shaft 136a "ellipse motion" is not necessarily a geometrical ellipse (a locus of points where the sum of distances from two fixed points (focal points) in a plane is constant). It does not have to be, and is meant to include non-true circles such as oval and asymmetrical circles.
