A moving member that causes a take-up shaft to rotate is prevented from passing through a limit position. In a webbing take-up device, a piston rises when a vehicle disposed with the webbing-take device experiences an emergency situation, whereby a pinion, a clutch plate, a lock gear, a torsion shaft and a spool are rotated, and a webbing is taken up. Thus, a flange of the piston abuts against a piston stopper fixed to a frame, and the rising energy of the piston is absorbed. Moreover, an upper end of the piston abuts against an inhibitor portion of a cover plate disposed at a limit position, and the rising of the piston is inhibited. Thus, the upper end of the piston causing the pinion to rotate can be reliably prevented from passing through the limit position.
