Abstract
A webbing retractor for taking up an occupant-restraining webbing used in a seat belt apparatus for a vehicle has a takeup shaft held by a frame, and the webbing is wound around the takeup shaft. The takeup shaft is pivotally held at a substantially intermediate portion of each of a pair of arms. One end of each arm is pivotally supported by a support shaft, and the arms are adapted to rotate about the support shaft. At the time of a sudden deceleration of the vehicle, a clamp plate held at a distal end of a clamp lever is pushed upward by an actuating device including the arms to cause the webbing to be clamped, and when a clamping force exceeding a predetermined value is applied to the webbing, a projection formed at a proximal end of the clamp lever presses a thin-walled portion toward a rectangular hole so as to deform the thin-walled portion, which in turn causes the clamp plate to move in a direction in which the clamped state of the webbing is canceled, thereby setting a webbing-clamping force at a predetermined level or below.
