Abstract

In a webbing tension device for imparting a tension to an occupant restraining webbing in an emergency situation of a vehicle, large biasing means for biasing a webbing takeup shaft in a webbing winding direction in the emergency situation of the vehicle is wound up by such winding-up drive means as a motor through reduction means and clutch means is disposed between the large biasing means and the reduction means. Accordingly, a rotation force of the winding-up drive means is transmitted to the large biasing means only when the large biasing means is wound up by the winding-up drive means.
