Further, a lead wire (not shown) for external connection is connected to a connector part (not shown) of the wiring board, and the switch part etc. is electrically connected to an electric / electronic circuit (not shown) of the vehicle. Is done.

(Operating state)
The operation state of the turning direction indicating device 50 according to the first embodiment will be described with reference to FIGS. FIGS. 6A to 6D are explanatory diagrams of a series of operations of the turning direction indicating device 50 according to the first embodiment.

  As shown in FIG. 6A, when the operation lever 3 is held in the neutral position and the steering is also in the neutral position, the cam body 8 is urged backward by the urging spring 10 in the direction of the cancel cam 11. In addition, the first shaft portion 8B is in elastic contact with the substantially triangular apex portion of the holding cam 2D. The rear cam portion 8E is located at a non-abutting position away from the rotation trajectory of the cancel cam 11, and the front cam portion 8D is located substantially in the middle of the opposing release protrusions 5A at both ends of the release body 5. ing.

<Right turn>
For example, when the operation lever 3 is pivoted clockwise in the clockwise direction in advance when turning the vehicle to the right, as shown in FIG. The actuator 2 is rotated together with the operating body 2 around the portion 2A (first axis C1), and is held by the moderation unit at the first operating position where the operating body 2 is rotated a predetermined angle clockwise.

  Similarly, when the operation lever 3 is rotated counterclockwise in the left direction, the operating body 2 is held by the moderation portion at the second operation position rotated counterclockwise by a predetermined angle from the neutral position. It has become.

  When the operating body 2 is held at the first operating position, the cam body 8 has the first shaft portion 8B slidingly sliding on the inclined surface from the apex portion of the holding cam 2D, in the vicinity of one end of a substantially triangular shape. The second shaft portion 8C moves rearward along the guide groove 9A.

  At this time, the rear cam portion 8E of the cam body 8 is retracted to the contactable position in the rotation track of the cancel cam 11, and the front end portion of the front cam portion 8D is the inner surface of the right release protrusion 5A. Proximity to.

  Further, as the operating body 2 rotates, the switch portion accommodated in the holding case 7 is electrically connected and separated, and the right side of the switch via the electric / electronic circuit of the vehicle is detected by the detection signal that is the switch signal. The turn signal lamp blinks.

  Next, when the steering wheel is turned clockwise in order to turn the automobile to the right, as shown in FIG. 6C, the cancel cam 11 interlocked with the steering rotates clockwise, After coming into contact with the rear cam portion 8E of the cam body 8, the cam body 8 rotates counterclockwise around the second axis C2 and is watched by the twist of the biasing spring 10 engaged with the engagement recess 8F. The front cam portion 8D moves away from the release protrusion 5A while increasing the energizing force around.

  Further, when the steering is continuously rotated clockwise, as shown in FIG. 6D, the rear cam portion 8E moves away from the cancel cam 11 with which the cam is in contact, and the cam body 8 is rotated clockwise by the cancel cam 11. The rotation restriction is canceled. Then, the cam body 8 is urged to rotate clockwise by the urging spring 10, and the front cam portion 8 </ b> D collides with the inner surface of the release protrusion 5 </ b> A on the right side of the release body 5.

  At this time, with the collision between the front cam portion 8D and the release protrusion 5A, the rear cam portion 8E of the cam body 8 easily jumps upward, and a collision occurs between the rear cam portion 8E and the upper edge portion of the opening 1A. . That is, the biasing spring 10 engaged with the engaging recess 8F presses the cam body 8 toward the upper surface of the second cover 9 at a position near the front of the first shaft portion 8B and deviated toward the front of the cam body 8. Therefore, the rear cam portion 8E located rearward from the first shaft portion 8B is likely to jump up.

  However, in this turning direction indicating device 50, the pin 12 and the elastic member 13 constitute a vertical urging means for urging the cam body 8 to the second cover 9 from a direction parallel to the second axis C2. Further, rattling of the cam body 8 in the direction perpendicular to the second cover 9 can be suppressed. As a result, jumping of the rear cam portion 8E of the cam body 8 can be suppressed, so that the collision noise between the rear cam portion 8E and the upper end of the opening 1A of the first cover 1 can be reduced, and the lower surface of the cam body 8 and The collision sound with the upper surface of the opposing second cover 9 can also be reduced.

  Further, when the turning of the automobile is finished and the steering is returned to the neutral position, if the steering is rotated in the counterclockwise direction opposite to the right direction, the cancel cam 11 is counteracted from the state shown in FIG. The cam member 8 rotates clockwise to press the rear cam 8E, the cam member 8 rotates clockwise about the second axis C2, and the right end of the front cam member 8D is connected to the operating member 2 via the release member 5. Is turned counterclockwise.

  Further, when the front cam portion 8D rotates the operating body 2 counterclockwise, the operating body 2 returns to the neutral position together with the operation lever 3 and returns to the neutral state, and the electric power of the switch portion is accordingly changed. The turn signal lamp that was flashing turns off.

<Turning left>
Similarly, when the vehicle is turned leftward, the operation lever 3 is swung to the second operation position counterclockwise in the left direction, thereby moving to the first operation position in the right direction described above. The operating body 2, the cam body 8 and the like operate in the direction opposite to the description at the time of the operation, and the left turn signal lamp blinks.

  At this time, when the steering is turned counterclockwise in the left direction, the left side surface of the front cam portion 8D is in contact with the left release protrusion 5A as the cancel cam 11 rotates counterclockwise. The cam body 8 rotates clockwise. Furthermore, after the cam body 8 strengthens the biasing force in the counterclockwise direction by the biasing spring 10, the cancel cam 11 is separated from the rear cam portion 8E, and the release protrusion 5A on the left side facing the front cam portion 8D. As a result of the collision, the rear cam portion 8E easily jumps up.

  However, as described above, in this turning direction indicating device 50, the vertical urging means for urging the cam body 8 to the second cover 9 from the direction parallel to the second axis C2 is constituted by the pin 12 and the elastic member 13. Therefore, rattling of the cam body 8 in the direction perpendicular to the second cover 9 can be suppressed. As a result, jumping of the rear cam portion 8E of the cam body 8 can be suppressed, so that the collision noise between the rear cam portion 8E and the upper end of the opening 1A of the first cover 1 can be reduced, and the lower surface of the cam body 8 and The collision sound with the upper surface of the opposing second cover 9 can also be reduced.

  Thus, according to the turning direction indicating device according to the first embodiment, the first cover 1 whose bottom surface is open, the second cover 9 disposed so as to face the first cover 1, and the one end are provided. Accommodated between the first cover 1 and the second cover 9 so as to be rotatable about the first axis C1 from the neutral position to the first operation position or the second operation position in accordance with the operation of the operation lever 3. The actuating body 2, the second cover 9 and the actuating body 2 are rotatably held around a second axis C2 disposed in parallel to the first axis C1 and the second The second shaft center C2 is held so as to be substantially linearly movable in the front-rear direction orthogonal to the shaft center C2, and the rear cam portion 8E provided at the rear portion is outward from the opening portion 1A provided at the rearward side of the first cover 1. The cam body 8 that protrudes and the upper surface that is the facing surface of the second cover 9 that faces the first cover 1 are locked, and the cam body 8 moves outward. And a biasing spring 10 that presses the cam body 8 on the upper surface of the second cover 9, and the rear cam of the cam body 8 in a state where the operating body 2 is located at the first or second operating position. The turning direction indicating device 50 that moves to a position where the portion 8E comes into contact with the cancel cam 11 and outputs a detection signal in response to the turning operation of the operating body 2, is a cam body from a direction parallel to the second axis C2. Vertical biasing means 12 and 13 for biasing 8 to the second cover 9 are further provided.

  When the operating body 2 rotates to the first or second operating position, the rear cam portion 8E is likely to jump up due to a collision with the release protrusion 5A of the release body 5 while the cam body 8 is urged to rotate. In addition, rattling of the cam body 8 in the direction perpendicular to the second cover 9 can be suppressed by the vertical biasing means 12 and 13. As a result, jumping of the rear cam portion 8E of the cam body 8 can be suppressed, so that the collision noise between the rear cam portion 8E and the upper end of the opening 1A of the first cover 1 can be reduced, and the lower surface of the cam body 8 and The collision sound with the upper surface of the opposing second cover 9 can be reduced. Therefore, it is possible to realize a turning direction indicating device that reduces the collision sound caused by the cam body 8 and quiets the operation sound.
