In a clamp housing there are arranged a swingable clamp arm and a hydraulic cylinder one before the other longitudinally, the clamp arm being pivotably supported near the lower end thereof to be freely swingable longitudinally, an elastic body is provided to extend from the clamp arm at the middle in height to a constituent member of the hydraulic cylinder so that the clamp arm is pushed back to be inward of the front face of the clamp housing in the absence of hydraulic oil pressure, while the clamp arm is driven forward by a piston of the hydraulic cyinder to be beyond of the front face thereof when sufficient oil pressure is provided to the hydraulic cylinder.
