Abstract:
1. A webbing retractor comprising: a clutch mechanism that is attached to a rotatable member rotating integrally with a spool rotatably supported by a frame, the clutch mechanism being capable of connecting the rotatable member and a ring unit positioned at a side of the frame, the clutch mechanism comprising: a lock member fixed to the rotatable member; a clutch cover that rotates integrally with the lock member; a clutch guide that is positioned between the clutch cover and the spool and is restrained from moving in an axial direction, the clutch guide being supported in a relatively rotatable manner with respect to the lock member, the clutch guide being capable of relatively rotating between an unactuated position and an actuated position with respect to the clutch cover, and the clutch guide being engaged with a trigger member positioned at a side of the spool and being held in the unactuated position; a spring that is in a compressed state and is positioned between the clutch cover and the clutch guide, and that urges the clutch guide held in the unactuated position toward the actuated position; a pawl that is positioned between the clutch cover and the clutch guide, and that is moved toward the ring unit and is engaged with the ring unit in accordance with the clutch guide being rotated from the unactuated position to the actuated position by the urging force of the spring in the event that the trigger member is disengaged from the clutch guide; and an axial-direction separation restricting mechanism that restricts axial-direction separation between the clutch cover and the clutch guide while allowing the relative rotation of the clutch cover and the clutch guide with respect to each other, the axial-direction separation restricting mechanism including: a hooked portion that is formed at one of the clutch cover or the clutch guide and that extends in a circumferential direction of the clutch guide; and a hook that is formed at the other one of the clutch cover or the clutch guide and hooks the hooked portion, wherein the hook is formed at the clutch cover, and the spring is latched by the hook.
