Claims

[Claim for Utility Model Registration] A cancel cam that is provided to rotate together with the steering shaft, and that is rotatably supported on a base on the side of the cancel cam and that can be turned from a neutral position to the left direction by operating a turn lever. a bracket that is rotated to a position and a right-turning direction position; two moderation walls provided on the base in a state that is spaced apart in the direction of rotation of the bracket; and a bracket that is movable to the bracket in response to these two moderation walls. two moderators provided in the bracket, biased by springs so as to come into pressure contact with corresponding moderation walls, and working together with the moderation walls to selectively hold the bracket in a neutral position, a left-turn direction position, and a right-turn direction position; It has two engaging convex portions provided on the outer circumferential portion thereof in a state of being spaced apart from each other in the rotating direction of the bracket, and is rotatably supported by the base, and the engaging convex portions are provided outside the rotational trajectory of the cancel cam. It is possible to rotate between a retracted position located at the retracted position and an inserted position where the engaging convex portion is located within the rotation locus of the cancel cam, and when the cancel cam is rotated in the state in which it is rotated to the inserted position, the engagement protrusion is rotated. A ratchet in which the cancel cam engages with the engagement convex portion and rotates to the retracted position; and the ratchet is held in the retracted position with the bracket held in the neutral position, and the bracket is moved from the neutral position to a left-turning position. or a ratchet holding mechanism that rotates the ratchet from the retracted position to the intrusion position and holds the ratchet in the intrusion position when the ratchet is rotated to the right-turn direction position; When the cancel cam is rotated in a direction opposite to the direction indicated by the bracket while the bracket is rotated to the left-turn position or the right-turn position, a moderation corresponding to the rotation of the ratchet by the cancel cam. 2. guiding the bracket to pivot to a neutral position by engaging and moving the bracket;
A turn signal cancel mechanism comprising two cancel guide parts.
