<p>PROBLEM TO BE SOLVED: To prevent occurrence of a canceling failure as much as possible, in a device having a function for escaping biting of so called a turn lever. SOLUTION: A ratchet for canceling comprises a ratchet body 31 and a ratchet movable portion 32 movable back and forth of the ratchet body 31, and a spring 40 for the movable portion is disposed between them. When the turn lever 24 bites, the ratchet movable portion 32 moves in the arrow G1 direction against a spring force of the spring 40. A vector F1 direction from the ratchet movable portion 32 to a pressed portion 29 differs from a moving direction of the ratchet movable portion 32 and a contracting direction of the spring 40 by substantially 90 deg. during a canceling operation, so that a vector F4 applying to the spring 40 is relatively small to reduce an effect on the spring 40.</p> |
