ABSTRACT:
In a webbing retractor, a spring member is caused to abut on a webbing takeup shaft to be rotated together therewith by a frictional force between the takeup shaft and the spring member within a range defined by rotation restricting means, locking means for preventing a webbing unwinding rotation of the takeup shaft is put in a released situation when the spring member is rotated in a direction of a webbing unwinding, and the locking means is put a locking situation when the spring member is rotated in a direction of a webbing winding. Accordingly, an occupant can be put in a surely restrained situation by the webbing when the webbing is wound on the takeup shaft in a slight amount after the webbing is worn on the occupant, though the webbing retractor has a simple construction.
