ABSTRACT:
An object of the invention is to provide at low manufacturing cost a clamp-operated retractor including an emergency locking mechanism adapted to lock the rotation of the winding shaft in the webbing pull-out direction in an emergency such as a collision, in which a webbing clamping mechanism is simple in structure, and is able to quickly stop the webbing from being pulled out. In a clamp-operated retractor according to the present invention, control means for moving a clamp 6 to a first position where pulling a webbing is prevented and a second position where pulling the webbing is permitted is composed of: a tension plate 9 which is so arranged as to be rotatable around the same axis as that of a latch plate 4a, and urges a latch cup 13 in a webbing winding direction, and rotatably supports a pawl 11; and a lever member comprising a clamp lever 7 and an outer plate 8 which are supported on side boards 1a in such a manner that the abutting part 8c of the outer plate 8 is engaged with an engaging portion 9d of the tension plate 9 and the slots 7f of the clamp lever 7 are engaged with the shaft of the clamp 6.
