Abstract: When end lock has occurred in a seat belt retractor due to winding-up of a webbing, the end lock is easily and surely released. A stop part (6G) engages with a lock arm (40) displaced in a locking operation direction and stops the lock arm (40). A lock mechanism (9), in a state where the lock arm (40) stands still on the stop part (6G), starts operation with rotation in a pull-out direction (P) of a winding drum and stops rotation of the winding drum. A transmission mechanism (19) transmits rotation of the winding drum to the lock arm (40) and displaces the lock arm (40) in a release direction to release the engagement with the stop part (6G) is released between the time when operation of the lock mechanism (9) is started and the time when rotation of the winding drum is stopped. Release means (18) releases the engagement between the lock arm (40) and the stop part (6G) by the transmission mechanism (19).

Abstract: A seat belt retractor instantly switchable between only winding of a webbing to winding and drawing-out of the webbing. Operation member 61 moves from a non-operation position E1 to an operation position E2, and locking mechanism 9 stops rotation of a winding drum in a drawing-out direction “P”. Movement member 70 moves an arrangement member 62 to a first position F1 or a second position F2, and arrangement member 62 arranges the operation member at the non-operation position E1 or the operation position E2. Urging means 63 urges the arrangement member 62 toward the first position F1. While winding a webbing 2, a second maintaining portion 77 of the movement member 70 maintains the arrangement member 62 at the second position F2. Release portion 78 of member 70 releases the arrangement member 62 toward a first portion 74, where the member 62 is kept at the first position F1.
