Claims

[Scope of utility model registration request]

a winding shaft for winding up webbing worn on an occupant; a mainspring spring for biasing the winding shaft in the webbing winding direction; and a first winding shaft fixed to the winding shaft and rotating together with the winding shaft. While meshing with the first gear, the rotation of the first gear in the webbing pulling direction causes the outer periphery of the first gear to revolve in the first direction, and the rotation of the first gear in the webbing winding direction causes the outer periphery of the first gear to be rotated in the first direction. A second gear revolves in a second direction opposite to the first direction, and by meshing with the second gear, the second gear moves in conjunction with the first gear, and the second gear rotates the outer periphery of the first gear in the first direction. A third gear is disengaged from the second gear by revolving, and a resistance force is applied to the third gear when the winding shaft is rotated in the webbing winding direction when the occupant is wearing the webbing. A webbing take-up device comprising: a resistance means for reducing the take-up force of a take-up shaft.
