International ClassesB60R 022/38B60R 022/40 AbstractA guide pin is provided erect at a lock plate of a webbing retractor. A guide hole is formed in a V gear in correspondence with the guide pin. The guide hole is formed from a first hole portion, a second hole portion and a third hold portion. A state in which the guide pin is positioned in the first hole portion is an initial state. When relative rotation between the V gear and a spool arises, the guide pin moves from the first hole portion and reaches the second hole portion. In this process, the guide pin pushes the V gear so as to rotate reversely, and locking is cancelled. When a pushing force causing a V gear reverse rotation angle to exceed a set value is applied from the guide pin, the guide pin escapes into the third hole portion such that excessive pushing force is cancelled. | |
