However, in such a conventional structure, the spherical portion is engaged with the inner spherical receiving portion on the side of the base member, that is, the two spherical surfaces are joined. As is known, since it is not easy to form a spherical surface with high precision, there is a problem in that the manufacture of a vehicle mirror becomes difficult. On the other hand, since the mirror adjusts the tilt angle only in the vertical direction and the horizontal direction, it is sufficient that the operation lever can swing in only two directions associated with this direction. Therefore, the operation lever swings not only in the above-mentioned two directions but also in all directions, so that there is a problem that it is difficult to perform the tilt angle adjusting operation.

[0004]

In order to solve the above-mentioned problems, the present invention is to mount a mirror housing on a base member fixed to the vehicle body, arrange the mirror in the mirror housing so that the mirror can be tilted, and operate an operating lever. In a vehicle mirror in which the tilting angle of the mirror is adjusted by means of the above-mentioned, a substantially cylindrical first portion which is provided with a receiving portion having an arcuate cross-section on the base member side and which is connected to the operation lever is provided. The rotating body is rotatably arranged, and the first rotating body is provided with a first arm for adjusting the tilt angle of either the left-right direction or the vertical direction of the mirror, and the first rotating body is provided with the first arm. The first rotating body is provided with a receiving portion having an arcuate cross section orthogonal to the rotation axis of the rotating body, and a substantially cylindrical second rotating body connected to the operation lever is rotatably arranged in the receiving portion. Left of the mirror on the rotating body Characterized in that a second arm for adjusting the direction or the other of the tilt angle in the vertical direction.

[0005]

The first rotating body is rotatably disposed on the receiving portion having an arcuate cross section formed on the base member side, and the second rotating body is rotated on the receiving portion having an arcuate cross section provided on the first rotating body. The mirrors are freely arranged, and the first and second arms are swung by the rotation of these two rotating bodies to adjust the tilt angles of the mirror vertically and horizontally. Therefore, it is possible to eliminate the bonding between the spherical surfaces as in the conventional case, and it is possible to easily manufacture the vehicle mirror. Further, since the rotation directions of the rotating bodies are respectively determined, the swinging direction of the operating lever is limited to two directions, and the operating lever does not swing in any direction as in the conventional case. It becomes easy to perform the adjustment operation of.

Next, an operation procedure of the angle adjusting device of the vehicle mirror device described above will be described. First, the operating lever 14
1 is rotated about the axis, that is, in the C and D directions in FIGS. 1 and 2, the swing rod 16 swings about the operation lever 14 in the vehicle front-rear direction, that is, in the direction perpendicular to the plane of FIG. , This swing is transmitted to the arm 23 via the connecting portion 26, and the arm 23
Swings in the front-rear direction of the vehicle body about the shaft 22. Here, as shown in FIG. 17, in the normal state, the engagement surfaces 22c ...
Since the side portion 36b of the spring 36 is engaged with the spring 36 with a constant elastic force, that is, the clutch 38 is in the contact state, the shaft 2
When 2 rotates around the axis (directions E and F in FIGS. 2 and 17), this rotation is transmitted to the arm 33 via the clutch 38, and the arm 33 rotates in the same direction about the shaft 22, that is, in FIG. It rotates in the E and F directions of FIG. This arm 3
By the rotation of 3, the ball portion 42b pushes and pulls the mirror holder 7 in the front-rear direction of the vehicle body, the mirror holder 7 tilts up and down with the pivot P as a fulcrum (directions G and H in FIG. 6), and the mirror holder 7 in FIG. Change the tilting position as shown on the imaginary lines c and d.

When the mirror holder 7 is tilted, the mirror holder 7 swings around the pivot P as described above, so that the position of the receiving portion 7a is in the vertical direction of the mirror holder (G and H directions in FIG. 6). It moves up and down with tilting.
For example, when the mirror holder 7 tilts in the G direction from the position indicated by the solid line in FIG. 6 and tilts to the position C, the receiving portion 7a moves rearward and moves downward by L2. This is because when the mirror holder 7 tilts, the receiving portion 7a draws an arcuate movement centering on the pivot P. And in this way the receiving part 7
When a moves downward, the spherical portion 42b of the connecting member 42 also moves downward together with the receiving portion 7a, but at this time,
The entire connecting member 42 moves downward. On the other hand, the operation lever 14 is moved along the elongated hole 9a in the vehicle front-back direction (I, J in FIG. 2).
Direction), the rotator 12 rotates about its axis, and the arm 13 swings around the rotator 12 in the longitudinal direction of the vehicle body. The swing of the arm 13 causes the arm 20 to move.
Swings around the shaft 19 in the front-rear direction of the vehicle body, and the shaft 19 rotates in the direction around the axis. Here shaft 1
As described above, since the springs 46, 46 are engaged with the engaging surfaces 19a, 19a of 9 with a constant elastic force, that is, the clutch 47 is in the contact state, the arm 44 moves the shaft 19 to the shaft 19 as in the case of the arm 33. It rotates in the vehicle front-rear direction (E, F direction), and the ball portion 52b pushes and pulls the mirror holder 7 in the vehicle front-rear direction by the rotation of the arm 44, and the mirror holder 7 tilts left and right with the pivot P as a fulcrum. Mirror M
The tilting angle of the left and right of is adjusted.

If a large force is applied to the mirror housing H from the front of the vehicle body and the mirror housing H is forcibly tilted rearward of the vehicle body, the bracket 3 is fixed to the housing H. The force is applied and the bracket 3 also moves. That is, the ball 4 is disengaged from the engagement hole 1b, and the bracket 3 is rotated around the fixed shaft 2 integrally with the housing H toward the rear of the vehicle body (direction F in FIG. 2). When the bracket 3 rotates rearward of the vehicle body, the mirror holder 7 pivotally supported by the bracket 3 also rotates rearwardly of the vehicle body together with the bracket 3. Further, since the spherical portions 42b and 52b are pivotally attached to the mirror holder 7, the arms 33 and 44 are attached to the shafts 22 and 19 respectively.
It rotates in the rear (F direction) of the vehicle centering around. When the arm 33 rotates in this direction, the clutch 38 is in the contact state, so that the shaft 22 rotates in the F direction in FIG. 17, that is, a force is input in the opposite direction to the normal force, and the arm 23, the connecting portion 26, and the swing rod. 1
The operation lever 14 rotates in the C direction via 6 and the like. or,
If the arm 44 rotates to the rear of the vehicle body, the clutch 4 is similarly moved.
The shaft 19 rotates in the F direction via 7, the rotating body 12 rotates in the direction around the axis via the arms 20 and 13, and the operating lever 14 swings in the I direction. Here, the range of rotation and swing of the operating lever 14 is limited in advance, that is, the swing of the operating lever 14 swings within the range of the tapered portion 12d of the hole 12c shown in FIG. The range is as much as possible, and the swing of the operation lever 14 is only within the range of the long hole 9a. Therefore, as described above, the arm 3
When 3, 44 rotate rearward of the vehicle body, the operation range of the operation lever 14 reaches the limit point in the middle of the rotation, and the operation lever 14
Stops moving. However, the arms 33 and 44 are still F
In this state, the clutches 38 and 47 are disengaged (disengaged state), and the forces on the arms 33 and 44 are prevented from being transmitted to the operation lever 14.

Explaining this with reference to FIG. 17, since the clutch 38 is in the contact state within the range in which the operation lever 14 can move, the rotation of the arm 33 is transmitted to the shaft 22 via the clutch 38 and the shaft 22. Rotates in the F direction. When the operating lever 14 reaches the limit and stops moving, the rotation of the shaft 22 stops and the arm 33 further rotates in response to this, so that the spring 36 stops at the large diameter portion 22b of the shaft 22 which is F. The side portion 36b of the spring 36 is disengaged from the engaging surface 22c, that is, the clutch 38 is disengaged, and the side portion 36b of the spring 36 is located at the top portion 22e of the large diameter portion 22b (see the imaginary line in FIG. 17). (State), further, the spring 36 idles around the outer periphery of the shaft 22, and the force on the arm 33 side is applied to the operating lever 1.
Prevent it from being transmitted to 3. In this embodiment, the operation lever 14
Although the arm 33 is rotated and the clutch 38 is disengaged even after reaching the limit and stopping the motion, the clutch 3
By making the operating torque of the operating lever 14 larger than the connecting / disconnecting load of 8, the clutch 38 can be disengaged without operating the operating lever 14. Clutch 4
The same applies to the case of 7 side, in which the spring 46 makes the shaft 1
When the clutch 47 is disengaged from the engaging surface 19a, the clutch 47 is disengaged, and the force on the arm 44 side is prevented from being transmitted to the operation lever 14 side.

In the above, according to this embodiment, the following effects can be obtained. First, the cylindrical rotating body 12 is rotatably engaged with the arcuate receiving portion 8f, and the cylindrical rotating body 15 provided on the operation lever 14 is rotated to the receiving portion (fitting hole) 12b having an arcuate cross section. Since they are freely engaged with each other, both engagements can be the engagement between the arcuate receiving portion and the cylindrical rotating body, and the conventional engagement between spherical surfaces can be eliminated. Therefore, it is possible to eliminate the molding work of the spherical surface, which is difficult to form when manufacturing the vehicle mirror,
This can facilitate the manufacture of the vehicle mirror. Further, in this embodiment, as described above, since the arcuate receiving portion and the cylindrical rotating body are engaged with each other, the rotating direction of the rotating body 12 and the rotating direction of the rotating body 15 are determined in the axial direction. Along with this, the operating direction of the operating lever 14 is also determined to be the accompanying direction, that is, the C and D directions in FIG. 1, and the I and J directions in FIG. Here, the tilt angle of the mirror M is adjusted by
Since only the up / down and left / right directions are required, the operation lever 14 only has to be swung in the two corresponding directions, and swinging in the other directions makes it difficult to adjust the tilt angle of the mirror M. In this embodiment, as described above, the operating lever swings only in the C and D directions of FIG. 1 and the I and J directions of FIG. 2 and does not swing in the other directions. It becomes easier to adjust the tilt angle of the mirror M. Further, in the present embodiment, the spherical engagement is abolished as described above, and the arcuate receiving portion and the cylindrical rotating body are engaged, and the receiving portion and the rotating body are engaged separately (rotating body 12 and the receiving portion 8f, the rotating body 15 and the receiving portion 12b), the contact area of the engagement surface can be increased, wear is small even after long-term use, and rattling can be prevented. You can On the other hand, in the present embodiment, as shown in FIG. 31, the rotation center line of the arm 13, that is, the rotating body 1
Since the rotation center line L of 2 is not perpendicular to the ground but has an inclination, when the arm 13 rotates about the center line L,
Since the horizontal portion 13a of the arm 13 is vertically displaced along with the rotation and the arm 13 is tilted rearward of the vehicle body in a plan view, as shown in FIG. Is the highest position, and the rear end position c is the lowest position, and the vertical displacement amount W is large. Therefore, in such a vehicle mirror, it is necessary to secure a space for the deviation of the horizontal portion 13a in the base member 1, but in the present embodiment, the rotation center line L is seen in a plan view as shown in FIG. Since the arms 13 are aligned in the length direction at the neutral position, the center of rotation L is tilted forward with respect to the vertical line segment V in a side view as a result, as shown in FIG. Therefore, as shown in FIG. 35, the vertical displacement amount W of the arm 13 is highest at the neutral position b, and the front end position b and the rear end position c
It is possible to minimize the vertical deviation amount W by making the vertical deviation amount W even at the neutral position b.

Further, the rotating body 12 is formed with a fitting hole 12b which constitutes a receiving portion in a direction orthogonal to the axis of the rotating body 12, and the fitting hole 12b is formed on the end side of the end portion of the operation lever 14, that is, the second side. 26, the portion constituting the rotating body 15 is rotatably fitted, and the end portion on the opposite side of the operation lever 14 passes through the elongated hole 9a as shown in FIG. As shown in FIGS. 26 and 28, an upper end of a swinging rod 16 which constitutes a second arm is fixed to a portion of the operating lever 14 inside the rotating body 12, that is, the rotating body 15.
