<p>The purpose of the present invention is to reduce the weight of an anchor in a pretensioner, and to simplify the structure of the anchor. A pretensioner (1) is used in a seatbelt device for a vehicle, and pulls on a seatbelt. A gas generation device supplies a gas to the interior of a cylinder (10). The gas supplied from the gas generation device moves a piston within the cylinder (10). A wire (60) is pulled by the piston and pulls the seatbelt, which is connected to a connecting part (61). An anchor (2) comprises a tubular member (2A) that covers the connecting part (61) of the wire (60) and is attached to the seatbelt. The connecting part (61) of the wire (60) is affixed to the tubular member (2A) while inserted in the tubular member (2A).</p> |
