ABSTRACT:
In a seat belt winding device with a clamping mechanism for directly holding a webbing in an emergency of a vehicle, since the plastic deformation is repeated in stages in both of a clamp supporting device and plastically deforming members, a larger amount of kinetic energy can be absorbed on the side of the seat belt winding device. Further, when the webbing holding by the clamping mechanism is removed, not only the diameter of a plastically deforming member of a bobbin can be reduced greatly since the plastically deforming members project in the radial direction of the bobbin, but also the deforming direction of the plastically deforming members due to the tightening of the webbing can be specified because end surfaces of the plastically deforming members are respectively formed in an inclined surface Which is inclined in a specific direction. This allows the substantial winding diameter of the bobbin to be reduced uniformly and positively.
