Abstract
A plate spring urges a base of a buckle device toward an anchor insertion opening side with respect to an anchor plate. Provided that urging force of the plate spring exceeds urging force of a spiral spring, the base is held, by the urging force of the plate spring, at a position at which a rivet contacts an insertion direction side end portion of a long hole. However, when the urging force of the spiral spring exceeds the urging force of the plate spring due to, in order to attach a child seat, pulling out of a webbing belt more than at a time when a body is to be restrained, the base moves against the urging force of the plate spring, and the plate spring pushes a transfer rod. Due to this pushing force being detected by a semiconductor diffusion strain gauge, it can be detected that the child seat is attached on a seat.
