Abstract
A seatbelt device for preventing a torque limiter mechanism from operating due to inertia force when a gear rotates quickly due to a winding force of an electric actuator, while maintaining satisfactory operating characteristics of the torque limiter mechanism. In the torque limiter mechanism, when a motor is driven to perform a wind-up operation, a prescribed operational torque that is set as a torque at which a limit spring moves from an engaging surface where the limit spring is positioned when a large-diameter side gear and a small-diameter side gear are in an assembled state, to an adjacent engaging surface, is greater than an operational torque at which the limit spring moves from the adjacent engaging surface to a next adjacent engaging surface by means of a shear pin.
