<p>Provided is a seatbelt device capable of 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 55 is driven to perform a wind-up operation, a prescribed operational torque which is set as a torque at which a limit spring 81 moves from an engaging surface 80g where the limit spring 81 is positioned when a large-diameter side gear 80 and a small-diameter side gear 82 are in an assembled state, to an adjacent engaging surface 80g, is greater than an operational torque at which the limit spring 81 moves from the adjacent engaging surface 80g to a next adjacent engaging surface 80g by means of a shear pin 83b.</p> |
