ABSTRACT:
A resilient member for biasing a webbing takeup shaft in a direction of retracting a webbing, after the webbing is fastened about an occupant, is driven in a direction of reducing the biasing force by a returning device, whereby the winding force acting on the webbing is reduced, so that an oppressive feeling rendered to the occupant can be reduced. After the webbing has been unfastened from the occupant, the returning device drives the resilient member in a direction of increasing the biasing force to retract the webbing to a fully retracted state.
