ベルトのプリローダ装置。[Scope of Claim for Utility Model Registration] (1) A deceleration sensor that detects, by displacement of an inertial mass, when a deceleration of a predetermined value or more is applied to a vehicle, and an ignition means that responds to the signal of the deceleration sensor. A preloader device comprising a drive device that applies a traction force to a seatbelt by the expansion force of a propellant that ignites and burns, and tensions the seatbelt that is stretched around the body of an occupant in the event of a collision, The deceleration sensor and the drive device are spaced apart from each other, and the deceleration sensor includes a shaft that rotates in response to displacement of the inertial mass, and there is a gap between the rotation shaft and the ignition means. A seat belt preloader device, characterized in that the seat belt preloader device is connected with a flexible torque transmission member. (2) The seat belt preloader device according to claim 1, wherein the ignition means utilizes frictional heat.
