Abstract
A preloader apparatus which retracts a buckle upon quick deceleration of a vehicle to tighten a webbing, and then restores the buckle to a position of ordinary vehicle running, to contemplate the improvement in operability of an operation button. The buckle is retracted upon quick deceleration of a vehicle from an ordinary protracted position to a retracted position through wires wound around a drum. After that, when a buckle-retracting force decreases and becomes smaller than a buckle-protracting force, a force F corresponding to a difference between the both acts on a projection, and the projection is broken. Although a meshing portion of a pawl meshes with an external tooth of an external gear to prevent the external gear from rotation in a direction of buckle protraction, the breakage allows the drum to rotate in the direction of buckle protraction, and the buckle can be restored to the protracted position. Projections abut against a stopper at the protracted position, and the buckle is prevented from further protraction.
