(Problem to be solved by the invention) In the conventional configuration, even if the operating lever is rotated from the neutral position to the left turn direction indication side or right turn direction indication side, when the rotation operation force is released, the operation lever returns to the neutral position. Since the contact holder automatically returns to its original position, just by looking at the switch case, you can tell whether the contact holder has been moved to the left-turn direction position or the right-turn direction position. It was impossible to determine whether this was the case.

The present invention was developed in view of the above circumstances, and its purpose is to check whether the contact holder, which causes the switch mechanism to perform a selection operation, is displaced to the left-turn direction position or the right-turn direction position by looking at the switch case part. To provide a turn signal switch device that can be determined by just one.

[Structure of the device] (Means for solving the problem) The device of the present invention can be rotated from a neutral position to the side indicating a left turn direction or the side indicating a right turn direction, and can be operated by pushing, and the operating force is released. An operating lever is provided on the switch case so as to automatically return to the neutral position when the switch is moved, and in conjunction with this operating lever, the switch is displaced from the intermediate position to the left-turn direction position and the right-turn direction position, and is held at the displaced position. A contact holder is provided in the switch case so as to be returned to the intermediate position by a pushing operation of a lever, and an indicator is provided that is displaced in accordance with the contact holder and instructs the direction of the displacement, and the contact holder is moved to the left when the contact holder is turned to the left. The configuration is such that a switch mechanism is provided that is selected depending on the displacement to the direction position and the right turn direction position.

(Function) In the turn signal switch device of the present invention, the contact holder is moved from the intermediate position to the left-turn position or the right-turn position in conjunction with the operating lever, and the switch mechanism moves the contact holder to the left-turn position or the right-turn position. A left-turn direction instruction operation or a right-turn direction instruction operation is selectively controlled according to the displacement of the contact holder, and the instruction section indicates whether the left-turn direction instruction operation or the right-turn direction instruction operation is selected by indicating the displacement direction of the contact holder.

In addition, engaging claws 31b are formed at the left, right and rear ends, and an arcuate projecting portion 31c is formed at the front end to project forward. Furthermore, on the back surface of this board 31 are fixed side contact pieces 33, 34 and 35 which together with the movable side contact piece 30 form a switch mechanism 32 (see FIG. 5).
are attached, and these fixed side contact pieces 33, 3
Terminal portions 33a, 34a, and 35a of terminals 4 and 35 protrude from the upper surface of the substrate 31, extend rearward, and are arranged parallel to each other. This board 31 is arranged so as to close the upper opening of the switch case 1, and has three engaging claws 31b.
are engaged with the engagement holes 11a of the three engagement protrusions 11, and the upper end of the shaft pin 5 is inserted into and engaged with the engagement hole 31a. As described above, when the board 31 is attached to the switch case 1, the contacts 30a of the movable side contact piece 30 are in contact with the fixed side contact piece 33, and the contact 30a of the movable side contact piece 30 is in contact with the fixed side contact piece 33.
0b is located between the fixed side contact pieces 34 and 35 (see FIG. 5). In the switch mechanism 32, when the fixed contact pieces 33 and 34 are short-circuited (turned on) by the movable contact piece 30, an energizing circuit is formed through the flasher unit of the left turn direction indicator lamp of the two-wheeled vehicle. Fixed side contact piece 33, 3
5 is short-circuited (turned on) by the movable contact piece 30, an electrical circuit is formed through the flasher unit of the right turn direction indicator lamp.

Next, the operation of this embodiment will be explained.

Now, the operating lever 12 moves the shaft pin 5 from the neutral position via the knob 18 in the direction of arrow A, which is the left turn direction indicating side.
When the pressure contact 21 is rotated around the guide surface 9b, the compression coil spring 20 is compressed and the pressure contact 21 slides along the guide surface 9b. presses the protrusion 25 of the contact holder 22 to the right, and the contact holder 22 is also rotated around the shaft pin 5 from the intermediate position in the direction of arrow A, which is the left-turning position. As a result, the ball 29 on the side of the contact holder 22 separates from the engagement recess 6 for the intermediate position and presses into engagement with the engagement recess 7 on the left-turning direction position. When the contact holder 22 is rotated in the direction of arrow A until the ball 29 engages with the engagement recess 7, one contact 30a of the movable contact piece 30 rotates integrally with the contact holder 22.
The other contact 30b comes into contact with the fixed side contact piece 34 while the contact 30b remains in contact with the fixed side contact piece 33, and the position between the fixed side contact pieces 33 and 34 is selectively turned on. As a result, an energizing circuit is formed through the flasher unit of the left turn direction indicator lamp.
The left turn direction indicator lamp flashes on and off to indicate a left turn direction. Furthermore, when the contact holder 22 is rotated in the direction of arrow A, the indicator 27 provided at the center of the cover 26 moves to the left so that it corresponds to the display 3 on the left. to indicate that a left turn direction instruction operation is in progress (see FIG. 6). Thereafter, when the rotation operating force on the operating lever 12 in the direction of arrow A is released, the pressure contact 21 begins to slide on the guide surface 9b toward the back wall 9a due to the spring force of the compression coil spring 20. Along with this, operation lever 1
2 is rotated in the direction opposite to the direction of arrow A and automatically returns to the neutral position. However, the contact holder 22 is held in the rotational position toward the left-turn direction position because the ball 29 is engaged with the engagement recess 7, and therefore, the left-turn direction indication operation by the left-turn direction indication lamp is not continued. That will happen. still,
When the operating lever 12 returns to the neutral position, its guide surface 15 comes close to the protrusion 25 of the contact holder 22. After that, when the operating lever 12 is pushed in, the operating lever 12 moves rearward against the spring force of the compression coil spring 20, and as a result of this movement, the guide surface 1
5 begins to press the protrusion 25 to the left, and as a result, the contact holder 22 is rotated in the direction opposite to the direction of arrow A, and the ball 29 is disengaged from the engagement recess 7 on the left-turning position side. Then, it is pressed into engagement with the engagement recess 6 again for the intermediate position, and thus,
Contact holder 22 is returned to the intermediate position.
Therefore, the contact 30b of the movable contact piece 30, which rotates together with the contact holder 22, comes off the fixed side contact piece 34 and is located between the fixed side contact pieces 34 and 35, and the fixed side contact piece 33 , 34 is now released (turned off). As a result, the energizing circuit of the left turn direction indicator lamp is turned off, and the left turn direction indication operation is canceled.

On the other hand, the operating lever 12 moves from the neutral position via the knob 18 in the direction of arrow B (arrow A
When the pressure contact 21 is rotated around the shaft pin 5 in the opposite direction), the pressure contact 21 comes to slide along the guide surface 9c, and when the operating lever 12 is rotated in the direction of arrow B, The guide surface 15 is the contact holder 2
The contact holder 22 is also rotated around the shaft pin 5 from the intermediate position in the direction of arrow B indicating the right turn direction. As a result, the ball 29 on the side of the contact holder 22 separates from the engagement recess 6 for the intermediate position and comes to be pressed into engagement with the engagement recess 8 on the right-turning direction side. Then, like this, the contact holder 22
When is rotated in the direction of arrow B, the contact 30b of the movable side contact piece 30 comes into contact with the fixed side contact piece 35, and the connection between the fixed side contact pieces 33 and 35 is selectively turned on. As a result, an energizing circuit is formed through the flasher unit of the right-turn direction indicator lamp, and the right-turn direction indicator lamp flashes on and off to perform a right-turn direction indication operation. Also, the contact holder 22 is
When the cover part 26 is rotated in the direction, the instruction part 27 of the cover part 26
moves to the right so that it corresponds to the right display section 4, thereby indicating that a right turn direction instruction operation is in progress (see FIG. 7). Thereafter, when the rotation operating force on the operating lever 12 in the direction of arrow B is released, the pressure contact 21 begins to slide on the guide surface 9c toward the back wall 9a, and as a result, the operating lever 12 is rotated in the direction opposite to the direction of arrow B and automatically returns to the neutral position. However,
The contact holder 22 has a ball 29 in the engagement recess 8
As a result, the turning position is held in the right-turn direction position, and therefore, the right-turn direction indication operation by the right-turn direction indication lamp continues. After that, when the operation lever 12 is pushed in, the guide surface 14 comes to press the protrusion 25 to the right due to the rearward movement of the operation lever 12, and as a result, the contact holder 22 moves toward the right side. The ball 29 is rotated in the opposite direction to the direction B.
The contact holder 22 is disengaged from the engagement recess 8 on the right-turning position side and comes into press-fit engagement with the engagement recess 6 for the intermediate position again, thereby returning the contact holder 22 to the intermediate position. Therefore, the contact 30b of the movable side contact piece 30 also comes off from the fixed side contact piece 35, and the contact 30b of the movable side contact piece 30 also comes off from the fixed side contact piece 3
The period between 3 and 35 is turned off. As a result, the energizing circuit of the right turn direction indicator lamp is cut off, and the right turn direction indicator operation is stopped.

As described above, according to the present embodiment, since the instruction section 27 is provided on the cover section 26 of the contact holder 22, after the operating lever 12 is rotated from the neutral position to the left turn direction instruction side or the right turn direction instruction side. Even when the switch is returned to the neutral position, the indicator 27 provided on the contact holder 22 held in the left-turn position or the right-turn position remains in a state corresponding to the display part 3 or 4 of the switch case 1. Therefore, by looking at the opening 2 of the switch case 1, the contact holder 22
It can be determined whether the position is displaced to the left-turn direction position or the right-turn direction position, and therefore it can be immediately determined whether the left-turn direction instruction operation or the right-turn direction instruction operation is selected.

In the above embodiment, the contact holder 22 is rotated and displaced in conjunction with the rotation of the operating lever 12, but the contact holder 22 may be displaced by linear movement instead.

Further, in the above embodiment, the contact holder 22 is provided with the instruction section 27, and the instruction section 27 is disposed integrally with the rotation of the contact holder 22, but the instruction section 27 may be displaced via an interlocking member instead. .

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but may be implemented with appropriate modifications within the scope of the invention, such as being applicable not only to motorcycles but also to various types of vehicles. Of course.

[Effects of the invention] As explained above, the turn signal switch device of the present invention is provided with an indicator that is displaced according to the contact holder and indicates the displacement position, so that the operating lever can be moved to the left turn direction indicating side or Even if it automatically returns to the neutral position by releasing the rotational force after being rotated in the direction indicating the right turn direction,
This has a practical effect in that it is possible to judge whether the contact holder is displaced to the left-turning direction position or the right-turning direction position simply by looking at the switch case portion.
