。The winding shaft on which the occupant restraint webbing is wound is urged in the webbing winding direction by the urging force of a small elastic body, and is blocked by the rotation trigger means of the actuation ring to which the rotational force of the large elastic body acts. The webbing tensioning device is a webbing tensioning device for forcefully winding the webbing by releasing the rotation prevention of the actuating ring by the trigger means and transmitting this rotational force to the winding shaft, the trigger means having a bowl that engages with the actuating ring; A webbing tensioning device comprising: a buckling means that maintains the engagement state between the bowl and the operating ring and buckles to release the engagement between the bowl and the operating ring when an acceleration of a predetermined value or more is applied.
