゛[Claims for Utility Model Registration] (1) A take-up shaft to which one end of the occupant restraint webbing is attached, and an elastic body whose one end is connected to the take-up shaft and urges the take-up shaft in the webbing winding direction. a rotating wheel that locks the other end of the elastic body and is rotatable relative to the winding shaft; and a driving means that drives the rotating wheel to change the biasing force of the elastic body.
A webbing take-up device comprising: a worm transmission means that is interposed between the drive means and the rotary wheel, supports an elastic body biasing reaction force acting on the surface of the rotary wheel, and does not reverse the drive means. (2) The elastic body is a mainspring spring whose inner end is fixed to the winding shaft and whose outer end is fixed to the rotating ring, and the mainspring spring is housed in a recess provided in the rotating ring. The webbing take-up device according to claim 1 of the utility model registration claim. -(3) The utility model characterized in that the worm means has a worm wheel carved on the outer periphery of the rotating ring, and a worm disposed on the driving means side of the worm wheel and meshing with the worm wheel. A webbing take-up device according to registered claim 1 or 2. (4) The rotating ring is rotatably supported relative to the winding shaft by a combination of a ring groove disposed coaxially with the winding shaft and a ring-shaped projection fitted into the ring groove. The webbing winding device according to any one of claims 1 to 3 of the utility model registration claim.
