Abstract
A locking mechanism applied to a retractor for winding up on a take-up shaft a webbing which fastens an occupant of a vehicle is designed to prevent the unwinding of the webbing when the vehicle suddenly decelerates. A lock wheel, that follows the rotation of the take-up shaft, maintains movable lock members rotating together with the take-up shaft at a position where the movable members are separated from fixed lock members. Upon sudden deceleration of the vehicle the lock wheel creates a rotational lag with respect to the take-up shaft, whereby the lock plates are engaged with the fixed lock members by the lock wheel, thereby preventing the rotation of the take-up shaft in a webbing unwinding direction. The movable lock members are pressed in the direction of the axis of the take-up shaft by an elastic body projected from the lock wheel, whereby clatter due to the vibrations of the vehicle is abolished.
