Abstract
In case a gas generating member of a pretensioner mechanism activates due to vehicle collision, a piston in a piston housing portion moves upwards from its normal position within a pipe cylinder. As a result, the piston comes in contact with a pinion gear portion and causes the pinion gear body to rotate abruptly. Further, a bottom end of a boss portion constituting one end portion of the pinion gear body is rotatably supported at a through hole of a base plate. Further, a support portion constituting the other end portion of the pinion gear body is rotatably supported at a support hole of a cover plate.
