Abstract
A lever is provided for switching from a state in which a preloader for rapidly rotating a webbing take-up shaft in a webbing winding direction in an emergency of a vehicle is non-operated to a state in which the preloader is operated. Before a retractor is mounted to the vehicle, the preloader is made non-operative so that an undesired operation may be avoided. The lever interlocks with a lock device for preventing the webbing take-up shaft from being rotated in a webbing pulling-out direction during acceleration of the vehicle. When the preloader is in a non-operative state, the lock device provides a locked state in which a webbing cannot be pulled out from the webbing take-up shaft. Therefore, in order to fasten the webbing to an occupant, the lever must be actuated to enable the pulling out of the webbing, i.e., to enable the lock device to operate and to enable the preloader to operate. After the retractor has been mounted to the vehicle, the preloader is released from the non-operating state.
