An embodiment of the present invention will be described below based on the drawings.

First, in Figures 1 to 3, 1 is a mounting base attached to the column cover through which the steering shaft passes, 2 is a cylindrical member provided on the mounting base 1 and through which the steering shaft passes, and 3 is a mounting base attached to the column cover through which the steering shaft passes. The cancel cam is rotatably provided with two protruding push pins 4 and 5, and is designed to be able to rotate together with the steering wheel. 6
is a main body case, which has a switch chamber 7 in the shape of a circular hole with a deep bottom, and a moderation parts storage chamber 8 with a shallow rectangular bottom connected to the switch chamber 7 at the top. The top surface of the parts storage chamber 8 is a lid 9
is closed by. Further, an opening 10 of a predetermined width extending vertically is formed in the right side wall of the switch chamber 7, and a hollow connecting portion 11 extends integrally from the left end of the moderation component storage chamber 8. The main body case 6 is connected at the distal end of the connecting portion 11 to the mounting base 1 by screwing means, and is located near the steering shaft and near the bottom of the steering wheel. Reference numeral 12 denotes a support shaft having circular pivots 12a, 12b on both the upper and lower sides and a prismatic shape formed between the two pivots 12a, 12b. arranged, each axis 1
2a and 12b are inserted and supported in bearing holes 13 and 14 formed in the lid 9 and the bottom wall of the switch chamber 7, respectively. Reference numeral 15 denotes a circular operating body, which has square holes 1 extending in the axial and radial directions and intersecting each other at right angles.
6 and 17 are formed, and the square hole 17 in the radial direction has a larger diameter than the square hole 16 in the axial direction.
The actuating body 15 is disposed within the switch chamber 7, and the support shaft 12 passes through a square hole 16 in the axial direction in a loose manner. Therefore, the actuating body 15 is connected to the support shaft 12
It rotates together with the support shaft 12 when the support shaft 12 rotates about its axis, and slides independently when the support shaft 12 moves in the axial direction. Reference numeral 18 denotes an operating lever having a square hole 19 at the base end and a knob 20 attached to the operating end, the base end of which is inserted into the main body case 6, and the operating end side is inserted from the main body case 6. Relatively long and protruding. That is, the base end of the lever 18 is inserted in advance into the square hole 17 of the operating body 15 through the opening 10 of the switch chamber 7, and the support shaft 12 passes through the square hole 19. Therefore, the lever 18 rotates around the support shaft 12 and rotates around the support shaft 12.
Regarding movement in the axial direction, the actuator 15 rotates integrally with the actuating body 15 and moves in the axial direction. In order to make the lever 18 movable by a predetermined amount along the square hole 17 of the actuating body 15, the square hole 19 of the lever 18 is
The opening width is limited to one direction and is set larger than the width of the support shaft 12 by a predetermined dimension. Note that 21 is a roller provided to reduce the sliding resistance between the actuator 15 and the support shaft 12 as much as possible to prevent the actuator 15 from twisting. Reference numeral 22 denotes a slide moderation mechanism for selectively holding the slide position of the actuating body 15 in four stages, upper and lower.
Reference numeral 3 denotes a holding hole formed in the lever 18 so as to open into a square hole 19, which accommodates a pressure contact 24 and a compression spring 25 for bringing it into elastic contact with one side of the support shaft 12. On the other hand, on one side of the support shaft 12 (the side corresponding to the opening 10 of the switch chamber 7) with which the pressure contact 24 comes into elastic contact, there are installed, in order from the bottom, OFF, small light, headlight low beam, and headlight high beam beams. Each valley 26 to 29
is formed. The compression spring 25 of the slide moderation mechanism 22 always biases the lever 18 in the direction of arrow A, and also serves as a spring for returning the lever 18 in the axial direction. Also, 30 and 31
are first and second movement converting members, which are arranged in parallel in the moderation component storage chamber 8 of the main body case 6, and are moved linearly from side to side in FIG. 3 using the inner surface of the storage chamber 8 as a guide. It is becoming possible to do so. 32

32a is provided protrudingly, and each of these protruding shaft portions 32a, 32
a are connected to elongated holes 33, 33 formed in the first and second movement converting members 30, 31 by insertion. Therefore, when the actuating body 15 is rotated clockwise in FIG. 3 via the lever 18, the first movement converting member 30 moves to the right as shown by arrow B, and the second movement converting member 31 moves to the right as shown by arrow C. When the lever 18 is rotated counterclockwise, the first and second movement converting members 30 and 31 are linearly moved in the opposite direction to the above. Reference numeral 34 denotes a rotation moderation mechanism, which selectively maintains the rotational position of the actuating body 15 in three stages by maintaining the relative positional relationship between the first and second movement conversion members 30 and 31. It is something to do. This rotation moderation mechanism 3
4, 35 is a holding hole formed in the first movement converting member 30 so as to be open on the surface facing the second movement converting member 31, and this holding hole has a moderation ball 36 and a holding hole for bringing it into elastic contact with the opposing surface. On the other hand, on the surface of the second movement conversion member 31 that is in contact with the first movement conversion member 30, there is an original position trough 38, and an action spring 37 located on the left and right sides of this trough 38 is provided. The positioning troughs 39 and 40 are formed.

are each formed with a notch.

Next, in FIGS. 5 and 6, 57 is a turn signal switch mechanism as a first switch mechanism, which is connected to the holding hole 5 formed in the operating body 15.
Compression spring 5 inserted into 8 for applying contact pressure
Movable contact 6 urged in the protruding direction by 9
0, and three terminal plates 61 to 6 implanted in the inner circumferential surface of the switch chamber 7 in parallel in the rotating direction of the actuating body 15 in correspondence with the movable contact 60.
3, and the terminal plate 61 in the center in Fig. 5.
is a power terminal board connected to the battery, the right terminal board 62 is a right turn indicator terminal board connected to a right turn indicator via a turn signal, and the left terminal board 63 is a left turn indicator terminal board connected to a right turn indicator via a turn signal. This is the terminal board for the left turn indicator light connected to. When the lever 18 is in the neutral position Po shown in FIG. The contact 60 connects the terminal boards 61 and 63 for the power supply and the left turn indicator light to blink the left turn indicator light.
8 is rotated from the neutral position Po to the right turn indication position Pb, the movable contact 60 connects the terminal plates 61 and 62 for the power supply and the right turn indication light to blink the right turn indication light. Note that the vertical length of each of the terminal plates 61 to 63 is the same as that of the operating body 15.
No matter where the movable contact 6 is located above or below,
0 is set to form the connection relationship as described above. 64 is a common power terminal plate for the small light switch mechanism 65 which is connected to the battery and constitutes a part of the second switch mechanism, and the daylight switch mechanism 66 which constitutes the remaining part of the second switch mechanism; 67 is the vehicle width A light terminal plate of a small light switch mechanism 65 connected to a small lamp such as a headlight, a tail light, etc.; 68 a low beam terminal plate of a daylight switch mechanism 66 connected to the low beam side of the headlight; 69;
is a high beam terminal plate of the daylight switch mechanism 66 connected to the high beam side of the headlight, and each of the above terminal plates is implanted in the inner circumferential surface of the switch chamber 7 in an arrangement relationship as shown in FIG. 70 and 71 are movable contacts inserted into holding holes 72 and 73 formed in the actuating body 15 and urged in the projecting direction by compression springs 74 and 75 for applying contact pressure, and these are the movable contacts of the small light switch mechanism. 65 and day switch mechanism 6
Can be used as a movable contact for 6. That is, when the lever 18 is in the off position O shown in FIG. 1 among the vertical positions, both movable contacts 7
0 and 71 are in contact only with the power supply terminal plate 64 (see the two-dot chain line in Fig. 5), and when it is raised one step from the off position O and set to the small light position T, the movable contacts 70 are connected to the power supply terminal plate and the light terminal plate 64. When the terminal plates 64 and 67 are connected to light only the small lamp (see Fig. 7a), and the lever 18 is raised one step from the small light position T to the low beam position Lo, the movable contact 70 turns on the power source. The movable contact 71 connects both terminal plates 64 and 68 for power supply and light, and lights up the headlight together with the small light on the low beam side. (see Figure 7b), raise the lever 18 one step further from the low beam position Lo to the high beam position H _I
When set to , the movable contact 70 connects the three terminal plates 64, 67, and 69 for power supply, light, and high beam, and lights up the headlight along with the small light on the high beam side (see Figure 7c). . Incidentally, the circumferential length of each terminal plate 64, 67 to 69 of the small light switch mechanism 65 and the daylight switch mechanism 66 is such that the movable contacts 70, 71 are arranged as described above, no matter which position the operating body 15 is rotated. are set to form a connection relationship. Reference numeral 76 denotes a passing switch mechanism configured to use the power supply terminal plate 64 and the high beam terminal plate 69 as its own terminal plates, and its movable contact 77 is attached to the base end of the lever 18 together with a compression spring 78 for applying contact pressure. The lever 18 is held in the opposite direction of arrow A when overtaking a vehicle in front.
When pressed in the direction, the movable contact 77 connects the terminal plates 64 and 69 for power supply and high beam to turn on the headlight on the high beam side, and when the pressure on lever 18 is released, lever 18 is released from the compression spring. It is automatically returned in the direction of arrow A by the spring force of 25. The movable contact 77 is configured to connect the terminal plates 64 and 69 by pressing the lever 18 no matter what vertical position or rotational position the actuating body 15 is in.

By the way, when the lever 18 (actuating body 15) is turned off,
The small lights, low beams, and high beams are held in each position by fitting the pressure contacts 24 of the sliding moderation mechanism 22 into the respective valleys 26 to 29. In this case, the headlights are held in the lighting side. In order to make the sliding of the operating body 15 known as a tactile sensation, the peak 79 between the small light trough 27 and the headlight low beam trough 28 is formed high. In addition, the lever 18 (actuating body 15) is held in each of the right turn and left turn instruction positions by using the moderation ball 36 of the rotation moderation mechanism 34 at the operating position trough 3.
9 and 40, and return from the indicated position to the neutral position is performed by canceling the cancel cam 3.
This is done by the cooperative action of the cancel lever 49 and the cancel lever 49. That is, for example, when turning left, the rotation moderation mechanism 34 is in a state as shown in FIGS. 8 and 9. In this state, when the steering wheel is returned and rotated after completing the turn, the push pins 4 and 5 of the cancel cam 3 come into contact with the lever portion 49b of the cancel lever 49 from the direction of arrow D, and the cancel lever 49 is moved around the shaft pin 47. In order to rotate it in the direction of arrow E, the cancel lever 49 comes into contact with the receiving piece 53 of the first movement conversion member 30 and pushes the first movement conversion member 30 toward the original position. Based on the second movement conversion member 3
1. The operating body 15 and lever 18 all return to their original positions. Furthermore, when the steering wheel is rotated to make a left turn, the push pin 4 of the cancel cam 3,
5 comes into contact with the lever portion 49b of the cancel lever 49 from the opposite direction of arrow D, and the cancel lever 49
is rotated in the opposite direction of arrow E, but in response to this rotation, the cancel lever 49 enters the recess 55 of the first movement conversion member 30, so the first movement conversion member 30 is moved in the direction of the original position. There's no way I'll let you do that. When turning right, as the steering wheel is rotated back, the press pins 4 and 5 of the cancel cam 3 come into contact with the lever portion 49b of the cancel lever 49 from the direction opposite to the arrow D, causing the cancel lever 49 to move in the direction opposite to the arrow E. In order to rotate the
The first and second movement converting members 30 and 31, the operating body 15, and the lever 18 return to their original positions in the same manner as when turning left.

According to the above configuration, the lever 18 is located near the steering wheel, and by rotating the lever 18 in the circumferential direction of the steering wheel, the actuating body 15 is rotated to operate the turn signal switch mechanism 57. , the operating body 15 is moved up and down by vertically moving the lever 18 in parallel to operate the small light switch mechanism 65 and the daylight switch mechanism 66, so it is easier for the driver than conventional systems. It becomes easier to operate. That is, in the conventional lever combination switch device, the lever is provided so that it can be rotated in the vertical direction, and a knob is also provided on the lever so that it can be rotated. The energized path was opened and closed, and the headlights were switched between low beam and high beam by moving the lever up and down. The reason for this is that the length from the pivot point of the lever to the operating end is long, so operating many switches by moving the lever up and down means that the range of rotation of the lever becomes large and the steering wheel This is because if the small light is too far away from the light, it becomes difficult to operate.In order to avoid this, the blinking of the small light and the opening and closing of the energized path of the headlight are controlled by a knob. On the other hand, in this embodiment, the lever 1
Since the actuating body 15 is moved up and down by parallel movement of the actuating body 15 in the vertical direction, even if many switches are operated by vertical movement of the actuating body 15, the lever 18 will not be far away from the steering wheel. Therefore, the turn signal switch mechanism 57, the small light switch mechanism 65, and the daylight switch mechanism 66 can be operated by a single lever 18, and by doing so, the lever 18 can be moved up and down. Even if the position needs to be changed in four steps, the lever 18 will not be far away from the steering wheel, improving operability. Furthermore, in this embodiment, the conventional switch for opening/closing the energizing path of the headlight is omitted, and the small light switch mechanism 65 and the daylight switch mechanism 66 are integrated into one location, so that the switch configuration is simplified.

As explained above, the present invention provides a support shaft approximately parallel to the steering shaft in the main body case attached near the steering shaft, and a lever that rotates and rotates the actuating body provided on the support shaft. The first switch mechanism is operated by rotating the operating body, and the second switch mechanism is operated by moving the operating body in the axial direction. , the first switch mechanism and the second switch mechanism can be operated with a single lever, and even if the amount of axial movement of the actuating body to operate the second switch mechanism becomes large, the lever can be operated by the steering wheel. To provide a lever combination switch device for a vehicle, which allows a driver to operate a lever while keeping his/her hand on a steering wheel without having to leave the steering wheel far from the steering wheel, thereby improving operability.
