ABSTRACT:
A section of a webbing between a takeup shaft and an occupant fastened portion thereof is guided around a roller pivotally supported on a rotatable plate, and the rotatable plate adapted to be rotated by an increased tension of the webbing is caused to approach a lock bar to clamp the webbing between the roller and the lock bar, whereby the movement of the webbing in the longitudinal direction thereof is prevented, so that an occupant can be restrained. The roller is prevented from rotating by lock means when the occupant is restrained, whereby the webbing is decreased in tension at the portion of the roller, so that an abrupt change in tension at the clamped portion of the webbing between the roller and the lock bar can be prevented, thereby enabling to avoid breakage of the webbing.
