Abstract
A preloader for use in a webbing retractor for retracting an occupant-restraining webbing forcibly onto a takeup shaft at the time of a sudden deceleration of a vehicle. The preloader includes a angular shaft rotating integrally with the takeup shaft; a deformable member disposed around the angular column shaft; and a wire connected to the deformable member and wound therearound. The wire is tightly wound around the deformable member at the time of a sudden deceleration of the vehicle, thereby causing the deformable member to undergo deformation and engage with the angular shaft. The angular shaft is hence rotated integrally with the deformable member so as to positively rotate the takeup shaft in a taking-up direction.
