Abstract
A canceling ratchet consists of ratchet body portion , ratchet movable portion enabled to move in a forward and backward direction in ratchet body portion , and a movable portion pushing spring provided between these portions. When a grabby brake phenomenon occurs in turn lever , ratchet movable portion moves in direction of arrow G against a spring force of movable portion pushing spring . When a cancel operation is performed, the direction of vector F differs by nearly 90 degrees from the direction of movement of ratchet movable portion , and from the direction of expansion and contraction of movable portion pushing spring . Thus, the magnitude of a vector F representing a force acting on movable portion spring is relatively small, exerting a small influence on the movable portion pushing spring.
