ABSTRACT:
In a seat belt retractor according to the present invention, lock actuating means is actuated to engage locking pins with the engagement portion of a frame when deceleration in excess of a predetermined value acts upon the vehicle and/or when the seat belt is pulled at an acceleration in excess of a predetermined value. Reliable engagement is achieved since the engagement portion of the frame is engaged by the locking pins, unlike the prior art which is adapted to mesh the teeth on a reel shaft with the teeth on a frame. Accordingly, the reel shaft is assuredly locked against turning in the seat belt pulling direction, as a result of which reliability is enhanced.
