The fixed contacts 32 and 33 are connected to turn signal lights 45 and 46 respectively mounted on the front and rear of the right side of the automobile, the fixed contacts 35 and 36 are connected to turn signal lights 47 and 48 respectively mounted on the front and rear of the left side of the automobile, and the fixed contact 38 is connected to a hazard warning light 49 mounted inside the automobile.
The actuators 50 and 51 are integrally provided with compression springs 52 and 53.
The small pieces 5 are always biased in the direction of the arrow B and the direction of the arrow C in the center of the first chamber 27.
The third operating element 1 of the bracket 3 is positioned in a butted state.
8 is inserted between the opposing actuators 50 and 51 through a long hole 54 formed in the case 21 .
A movable contact 55 is attached to the underside of the first actuator 50, and constitutes a first switch mechanism 56 together with the fixed contacts 31 to 33.
The second actuator 51 is in constant contact with the fixed contact 31. The second actuator 51 has a movable contact 57 attached to its underside, which constitutes a second switch mechanism 58 together with the fixed contacts 34 to 36 and is in constant contact with the fixed contact 34. The first interlocking member 59 is slidably disposed within the second chamber 28, and one end of the first interlocking member 59 is connected to a seesaw-shaped push button 60 which is an operating member for a hazard signal.
A protrusion 59a is integrally provided on one side of the center of the partition wall 30 and protrudes between the actuators 50 and 51 through a hole 61 formed in the partition wall 30.
The first actuator 50 is brought into contact with the second actuator 50. The movable contacts 62 and 63 are attached to the lower surface of the second interlocking member 59.

The other movable contact 63 constitutes a switch 65 for switching the power supply path together with the fixed contacts 39 to 41, and is normally connected to the fixed contacts 40 and 41.
Reference numeral 66 denotes a second interlocking member having a shaft portion 66a at its center and arms 66b, 66c extending from both sides thereof, the shaft portion 66a being rotatably inserted and supported in bearing holes 67, 68 formed in the switch base 20 and the case 21, respectively, one arm 66b being inserted into a notched groove 69 formed in the lower center portion of the second interlocking member 59, and the other arm 66c being inserted between the two actuators 50 and 51, so that the arm 66c is connected to the second actuator 51.
When the first interlocking member 59 slides in the direction of the arrow D, the arm 66b of the second interlocking member 66 is pressed against the right side of the notched groove 69 of the second interlocking member 59 in FIG. 3, so that the first interlocking member 66 rotates in the direction of the arrow E around the shaft 66a.

Next, in the above configuration, when the operating lever 7 is rotated from the neutral position PN to the left turn instruction position PL in order to turn left, for example, the third operating element 18 moves to the bracket 3.
At the same time, it rotates about the hollow support shaft 4 in the direction of arrow F from the position shown in FIG. As a result, the second operating element 51 is pressed by the third operating element 18 and slides in the opposite direction of arrow C against the elastic force of the compression spring 53, from the position shown in FIG. 3 to the position shown in FIG. 7. In order to move into position, the fixed contacts 34 to 36 of the second switch mechanism 58 are interconnected by a movable contact piece 57. Therefore, the direction indicator light 47 on the left side of the car
and 48 are connected to the battery 42 via the flasher 44, the fixed contact piece 40, the movable contact piece 63, the fixed contact piece 41, and the ignition switch 43, and are operated to flash to issue a turn signal for left turn. When the steering wheel is returned after turning left, the cancel mechanism is actuated by the return operation to automatically return the operating lever 7 to the neutral position together with the bracket 3. Therefore, the third operating element 18 also moves in the direction opposite to the arrow F direction. Return to the position shown in Figure 3. Then, following the return movement of the third operator 18, the second operator 51 slides in the direction of arrow C due to the elastic force of the compression spring 53 and returns to the position shown in FIG. The fixed contact pieces 35 and 36 are disconnected from the piece 34, and the blinking operation of the left direction indicator lights 47 and 48 is stopped. Note that when the operating lever 7 is rotated from the neutral position PN to the right turn instruction position PR in order to turn right, the third operating element 18 also rotates in the direction opposite to the arrow F, and the first operating element 50 is rotated in the opposite direction to the arrow F. By sliding it in the B direction, the fixed contact pieces 31 to 33 of the first switch mechanism 56 are connected to each other by the movable contact piece 55, so that the right direction indicator lights 45 and 46 are activated in the same way as in the case of left turn. flashes and issues a right turn signal.

Now, if there is a malfunction in the car and it is necessary to issue a hazard signal, push button 60 can also be pressed by arrow G.
It is operated by pressing so that it rotates in the direction. Then, in conjunction with the rotation of the push button 60, the second interlocking member 59 slides in the direction of arrow D, and as the interlocking member 59 slides, the second interlocking member 66 also slides.
rotates in the direction of arrow E. In this way, when the first interlocking member 59 and the second interlocking member 66 operate in conjunction with the rotational operation of the push button 60 to move the protrusion 59a and the arm 66c, which are the respective operating parts, in opposite directions, the The first actuator 50 is brought into contact with the protrusion 59a of the first interlocking member 59, and the compression spring 5
Slide in the opposite direction of arrow B against the elastic force of 2,
Further, the second actuating member 51 is brought into contact with the arm 66c of the second interlocking member 66 and slides in the opposite direction of arrow C against the elastic force of the compression spring 53. Therefore, when the push button 60 is rotated in the direction of the arrow G, the first and second interlocking members 59 and 6
6. The first and second actuators 50 and 51 have moved to the positions shown in FIG. The connection is switched between the contact pieces 39 and 40. Further, the fixed contact pieces 31 to 33 of the first switch mechanism 56 are connected to each other by a movable contact piece 55, and the fixed contact pieces 34 to 36 of the second switch mechanism 58 are similarly connected to each other by a movable contact piece 57. ing. Therefore, all of the direction indicator lights 45 to 48 and the hazard indicator light 49 are connected to another energization path that does not go through the ignition switch 43, that is, the flasher 44, the fixed contact piece 40, and the movable contact piece 63.
and is connected to the battery 42 via the fixed contact piece 39, and the direction indicator lights 45 to 48 all blink to issue a hazard signal, and the hazard indicator light 49 also blinks to cause all the direction indicators 45 to 48 to blink inside the vehicle. 48 blinks to indicate that it is in operation. When the push button 60 is rotated in the direction opposite to the arrow G to stop the hazard signal, the first interlocking member 59 slides in the direction opposite to the arrow D and returns to its original position. is slid in the direction of arrow B to follow the movement of the protrusion 59a of the first interlocking member 59 in the opposite direction of arrow D due to the elastic force of the compression spring 52, and returns to its original position. 51 also rotates the second interlocking member 66 in the opposite direction of arrow E due to the elastic force of the compression spring 53 and slides in the direction of arrow C to return to its original position, and as a result of the above, the turn signal lights 45 to 48 and the hazard display The blinking operation of the light 49 stops.

Note that the first and second interlocking members are not limited to the configuration of the first embodiment, but may be configured as shown in FIG. 9 showing the second embodiment. That is, in FIG. 9, the first interlocking member 70 and the second interlocking member 71 are slidably disposed on both sides of the first and second actuators 50 and 51, and one end of both the interlocking members 70 and 71 is are connected to opposite sides of the rotation center of the push button 60, and both actuators 5 are connected to both interlocking members 70 and 71, respectively.
A protrusion-shaped acting part 70a interposed between 0 and 51,
71a is integrally provided in a protruding manner. With such a configuration, when the push button 60 is rotated in the direction of arrow H to issue a hazard signal, the first interlocking member 7
0 and the second interlocking member 71 are interlocked with the rotation of the push button 60 in the arrow H direction, and the arrow I is in the opposite direction.
The operating portion 70a of the first interlocking member 70 slides the first actuator 50 in the direction of the arrow K against the elastic force of the compression spring 52, and The acting portion 71a of the interlocking member 71 slides the second actuator 51 in the direction of arrow L against the elastic force of the compression spring 53 (see the two-dot chain line in FIG. 9). Therefore, as in the first embodiment, by rotating the push button 60,
All direction indicator lights 45 are removed by sliding the first actuator 50 and the second actuator 51 in opposite directions.
48 and the hazard indicator light 49 can be operated to blink.

As explained above, in the present invention, when the turn signal operating member is operated in one direction, the first actuator operates independently, and when the operating member is operated in the other direction, the second actuator is operated independently. In addition, first and second interlocking members are provided that operate in conjunction with the operation of the operating member for the hazard signal, and the first and second interlocking members are operated by the operation of these interlocking members. Since the actuators are configured to operate together, the first and second switch mechanisms, which are opened and closed by the first and second actuators, can be used as both a turn signal switch and a hazard signal switch. To provide a signal switch device for an automobile that has a simpler switch configuration and can be manufactured at a lower cost than in the past in which both turn and hazard switches are provided separately and independently.
