Abstract
A main shaft is threadably coupled to a base mounted on a vehicle body, and this main shaft is biased by a spring in the axial direction thereof. However, the main shaft is prevented from rotating by an arm tiltably supported on the main shaft being engaged with a stopper provided on the base. In an emergency of a vehicle, an acceleration sensor turns the arm to slip off the stopper to make the main shaft rotatable, whereby the main shaft rotatingly moves in the axial direction thereof. This moving force is transmitted to the webbing, whereby the webbing is retracted, so that the webbing can be closely fastened to an occupant.
