Claims

[Scope of utility model registration request]

A switch base on which a turn lever for operating a turn signal switch is rotatably mounted, and an operation that is provided on the switch base so as to be movable back and forth between an OFF position and an ON position, and is always biased toward the OFF position. A hazard switch comprising a knob, a heart-shaped cam provided integrally with the operating knob, and a locking mechanism that has a lock pin that is locked to the lock pin and holds the operating knob in the on position in a locked state. In the apparatus, the heart-shaped cam is provided to be vertically displaceable with respect to the operating knob, and a cancel convex portion is provided on the turn lever to correspond to the heart-shaped cam, and the operating knob is located in an on position. When the turn lever is rotated from the neutral position in a predetermined direction, the cancel convex portion presses the lock pin from the side to release the lock pin from the heart-shaped cam, and the turn lever moves to the predetermined position. When the operating knob is operated from the OFF position to the ON position, the lock pin is pressed downward by the cancel convex part and the heart-shaped cam is displaced downward, causing the heart-shaped cam to move. A hazard switch device characterized in that it is locked.
