Abstract
A seat belt retractor incorporated in a seat back that does not create noise, even with the vibration of a vehicle. A reel is supported by a frame, and reel rotation is prevented by a locking mechanism. In the locking mechanism, rotation of a gear wheel is prevented by an acceleration sensor, and a trigger is pivoted through a clutch wheel to engage a tooth portion with teeth on a lock ring, thereby stopping rotation of an intermediate wheel. Ratchets are supported by a ratchet wheel associated with the intermediate wheel. Since the ratchet wheel rotates even after stopping rotation of the intermediate wheel, the ratchets move outward whereby a stopper is pressed down. This cancels the engagement between a rack on a sensor holding portion and a rack of the stopper.
