Abstract

Provided is a seat belt device, which can cut the connection between a spindle for winding up a seat belt and an electric actuator reliably, when a pretentioner mechanism acts, thereby to constrain a passenger reliably at the pretentioner acting time. When a pretentioner mechanism (15) acts so that an engaging portion (49a) moves in the direction away from a first rotary member (50) while using the rotation of the first rotary member (50) by the pretentioner mechanism (15), a clutch (52) is elastically deformed by an engaging member (49) so that it regulates the movement of the engaging member (49), thereby to uncouple an electric actuator(34) and a spindle (12). The engaging member (49) rocks such that the engaging portion (49a) engages with an engaged portion (50a). A guide portion (43b) guides an extending portion (49c) extending to the opposite side of the engaging portion (49a) with respect to the hinge pin of the engaging member (49). The guide portion (43b) includes a radial guide portion (43a) for guiding the extending portion (49c) to move radially outward, as viewed from the center of the first rotary member (50). The radial guide portion (43a) has such a face to contact the extending portion (49c) as has a center of curvature toward the extending portion.
