ABSTRACT:
A retractor having a clamp is provided for use in a seat belt system. The retractor comprises a base, a take-up spindle rotatably supported on the base, a webbing wound on the take-up spindle, a clamp movement limiting member, a holding mechanism for holding the clamp movement limiting member on a base via a plastically deformable member, the clamp movable between a first position where the clamp holds the webbing between itself and the clamp movement limiting member and a second position wherein the clamp permits free passing of the webbing, a transmitting member for bringing the clamp from the second position to the first position in response to rotation of the take-up spindle in a webbing releasing direction, and a connecting member for releasably connecting the transmitting member to the take-up spindle. When the clamp is brought to the first position by the transmitting member and a pulling force of at least a predetermined value is then applied to the webbing, the plastically deformable member undergoes deformation while maintaining a webbing clamping force, thereby permitting movement of the clamp movement limiting member in the webbing releasing direction.
