<p>In a front portion of a clamp housing 2 a guide bore 16 for a clamping member 5 is formed in the backwardly acclivous direction. In a rear portion of the clamp housing 2 a cylinder bore 18 of a hydraulic cylinder 17 is formed horizontally in the forward and backward direction. An engagement projection 31 is disposed before a piston 19 and an engaged groove 35 is formed in the clamping member 5 so that the projection 31 is fitted into the groove 35 relatively movably in the vertical direction. By moving the projection 31 in the forward and backward directions by means of the piston 19 the projection 31 actuates the clamping member 5 in the inclined direction. <IMAGE></p> |
