ABSTRACT:
A tension reducer used in a webbing retractor is provided with a weak coil spring, a strong coil spring, and a connecting member all connected in series, the rotation of the connecting member in the webbing winding direction being stopped at a predetermined time after the webbing has been pulled out from the winding shaft when a passenger puts on the webbing. The inner end of the weak coil spring is connected to the connecting member so that, after the rotation of the connecting member has stopped, the urging force of the spring is released as the spring unwinds from its outer end.
