Abstract
In a pretensioner device, engaging teeth of a pinion (rotating body) have first projections which project-out toward the other side in the peripheral direction of a cam portion. Meshing claws of a clutch plate have second projections which project-out toward a one side in the peripheral direction of the cam portion, and whose gear portion side end surfaces face the first projections. In a state before operation of the pretensioner device, movement of the clutch plate toward one side in the axial direction with respect to the pinion is restricted due to the second projections engaging with the first projections. Accordingly, in the pretensioner device, in the state before operation, even if some type of external force is applied to the clutch plate, positional offset of the clutch plate toward the one side in the axial direction with respect to the pinion can be prevented.
