ABSTRACT:
A retractor has a webbing take-up shaft rotatably supported in a base, a biasing member for biasing the take-up shaft in a webbing take-up direction, a connecting member for connecting one portion and another portion of the biasing member, a locking member movably provided in the base and engageable with the connecting member, and a control device for controlling the condition of the locking member. The locking member is capable of assuming a locking position in which it is engaged with the connecting member to prevent the biasing force of the other portion of the biasing member from acting on the take-up shaft and a non-locking position in which it is in non-engagement with the connecting member to permit the biasing force of the one portion and the other portion of the biasing member to act on the take-up shaft, and when the locking member is brought to the locking position by the control device, it is movable away from the connecting member when the connecting member moves with the take-up shaft rotating in a webbing draw-out direction.
