Claims

[Scope of utility model registration request]

(1) A frame that is attached to the vehicle body, a pair of take-up shafts that are pivotally supported on this frame and wind up the occupant restraint webbing, a ratchet wheel that is fixed to each of the pair of take-up shafts, and a shaft that is attached to the frame. a pair of locking members supported and capable of meshing with the ratchet wheel; a vehicle acceleration sensor provided corresponding to one of the winding shafts and activated in the event of a vehicle emergency; and transmitting the operation of this sensor to the pair of locking members. and a transmission means that engages the ratchet wheel with each other, but allows the pair of locking members to be moved separately in a direction away from the ratchet wheel when a force exceeding a predetermined value is applied.

(2) The transmission means transmits the operating force of the acceleration sensor to each locking member through the elastic body, so that when a force exceeding a predetermined value is applied, the elastic body flexes to separately ratchet the pair of locking members. The webbing retractor according to claim 1, wherein the webbing retractor is movable in a direction away from the foil.
