Abstract
A pretensioner device in which, at a time of rapid deceleration of a vehicle such as a collision, a gas generator generates gas and the pretensioner device moves a piston in a direction of tensing a webbing. When, due to delayed detection by an acceleration sensor, the gas generator operates after a stretch-out load has been applied to a wire, high-pressure and high-temperature gas within a gas chamber contacts a guard pipe, which is formed of a material having a high thermal conductivity and is disposed within the gas chamber, and is cooled, and passes through a clearance and a pin hole communicating regions to a front and rear of the piston, and is discharged into a cylinder.
