摘要： PURPOSE: To stably clamp an indefinite form-shaped workpiece by providing a clamping belt, deformed to copy a shape of the workpiece by extending/ contracting a cylinder so as to clamp the workpiece, between a bracket and a fork in an X shape. CONSTITUTION: A tip end of fingers 10a, 10b and a bracket 2 are connected by clamping belts 15a, 15b, to connect a tip end of a finger 11 and the bracket 2 by a clamping belt 16, and the clamping belts 15a, 15b are crossed with the clamping belt 16 in an X shape. By extending/contracting clamping belt tensile cylinders 14a, 14b of connecting forks 3a, 3b to the fingers 10a, 10b and a clamping belt tensile cylinder 14c of connecting a fork 5 to the finger 11, tension of the clamping belts 15a, 15b, 16 is adjusted. By adjusting this oil pressure, tension of the clamping belts 15a, 15b, 16 can be adjusted. Consequently, needless to say a hard object and even a soft object can be clamped without flawing.
