Abstract
In a pretensioner mechanism, movement of a piston is anchored by an anchoring pin. The anchoring pin is crushed and the piston is allowed to move. Hence, a pinion is turned by a rack of the piston. A facilitating cavity is formed in the anchoring pin. Crushing and deformation of the anchoring pin in a diametric direction thereof due to a movement of the rack is facilitated by the facilitating cavity. Therefore, the anchoring pin may be easily crushed and deformed in the diametric direction by the movement of the rack, and the action of the anchoring pin caused by the movement of the rack may be effectively made consistent.
