Abstract
A cancelling mechanism for a turning signal automatically returns an operation lever which has been operated in order to indicate the turning direction of a vehicle to a neutral position by the rotation of a steering shaft in the direction opposite from that in which the operation lever is operated. The cancelling mechanism includes a bracket for supporting the operation lever. The bracket is rotated from the neutral position to a right turn position or a left turn position by the pivot of the operation lever. The cancelling mechanism also includes a member for transferring to the bracket the rotary force of a cancelling cam rotated by the rotation of the steering shaft in the direction opposite from that in which the bracket is rotated so as to return the bracket to the neutral position. An elastic member is provided between the bracket and the transfer member. In consequence, the durability of the cancelling mechanism is improved.
