<p>In order to provide a pretensioner which can enhance the reliability of a restraining function of a push-in displacement of a wire, a wire-holding groove (22) is formed in a housing (21) at a bent portion, so that a wire (23), which holds a seat belt buckle (27) at an upper end protruding from the wire-holding groove (22), is slidably held by the wire-holding groove (22). The wire (23) slides and is displaced in a draw-in direction of the seat belt buckle (27) when a gas generator (35) is actuated and acts on a part of the wire (23) closer to an end thereof, which extends in a front-to-back direction of a vehicle. The tongue piece (21a) bulging into the wire-holding groove (22) restrains the wire (23) from being pushed in due to a push-in load of the wire from the seat belt buckle (27). Conversely, the wire (23) is allowed to be drawn in upon the actuation of the gas generator (35).</p> |
