ABSTRACT:
Disclosed herein is a webbing retractor suitable for use with a vehicle seat belt. It comprises a casing equippd with a pair of side plates, a take-up spindle, a cogwheel provided outside one of the side plates in such a way that is allowed to rotate together with the take-up spindle, a lock member supported directly or via an attachment member by at least one of the side plates in such a manner that the lock member is displaceable between a first position where it is kept in engagement with the cogwheel and a second position where it is out of engagement with the cogwheel, and an auxiliary plate disposed outside the cogwheel substantially as an integral unit with the one of the side plates. When an undue force is exerted on the take-up spindle, at least either one of the take-up spindle, the cogwheel and the lock member or attachment is brought into engagement or contact with the auxiliary plate and the webbing retractor is thus protected from any further deformation.
