ABSTRACT:
A webbing retractor in which a retracting shaft for winding up a webbing is urged by a pair of resilient members connected in series through a ratchet wheel to cause the webbing to be wound around the retracting shaft, and a pawl is disengageably meshed with the ratchet wheel by a friction spring which is transmitted a rotation of the retracting shaft through a frictional force so that an urging force of one of the resilient members is prevented from transmitting to the retracting shaft during engagement of the pawl with the ratchet wheel, wherein a reduced condition of the webbing retracting force is able to be maintained over a wide range.
