<p>A guide pin (16h) is formed at a lock plate (16) of a webbing retractor. A guide hole (18b) is formed in a V gear (18) in correspondence with the guide pin. The guide hole is formed from a first hole portion (60), a second hole portion (62) and a third hold portion (64). A state in which the guide pin (16h) is positioned in the first hole portion is an initial state. When relative rotation between the V gear (18) and a spool arises, the guide pin moves from the first hole portion (60) and reaches the second hole portion (62). In this process, the guide pin (16h) pushes the V gear (18) 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 (64) such that excessive pushing force is cancelled. <IMAGE></p> |
