<p>PURPOSE: To reduce the collision sound generated when the ratchet of a self- cancel mechanism is returned after passing through the cam projection of a cancel cam. CONSTITUTION: A projection 41 is formed at the portion 35a of a ratchet 35 on the opposite side to a cancel cam, and a ridge section 43 is formed on the cover 23 of a body. When the ratchet 35 is returned after passing through the cam projection of the cancel cam at the indication position of the right turn or left turn of a bracket, the projection 41 is brought into friction contact with the ridge section 43, then a collision is mitigated, and the generation of collision sound is suppressed.</p> |
