Claims

[Scope of utility model registration request]

a take-up shaft for winding up webbing worn on an occupant; a first mainspring spring whose inner end is connected to the take-up shaft to urge the take-up shaft in the webbing winding direction; and the take-up shaft; a gear wheel which is coaxially disposed to be rotatable relative to the winding shaft and to which the outer end of the first mainspring spring is locked; a second mainspring spring biased in the winding direction; a first position engaging the gear wheel to stop the biasing force of the second mainspring spring; and a second mainspring spring spaced apart from the gear wheel.
a pole movable to a second position where the biasing force of the mainspring spring is released; biasing means biasing the pole toward the first position; When the webbing exceeds a predetermined amount, the pole is pressed to the second position against the biasing force of the biasing means, and when the webbing is pulled out from the take-up shaft by a predetermined amount or more, the pressure on the pole is released. and a pressing member that allows the pole to be moved to the first position by the urging of the urging means.
