。 A piston is slidably fitted into the cylinder body to form a divided working chamber, and the piston is actuated by a working tool protruding from one end of the piston and a connected operating shaft protruding from the cylinder body using pressurized fluid. It has a hydraulic cylinder to be operated, and an operating shaft passes through the piston of the hydraulic cylinder.When the pressure in one working chamber becomes higher than a predetermined pressure difference with respect to the pressure in the other working chamber, it opens and opens the valve between the two working chambers. A control valve body is provided for communication, and a free piston is slidably fitted into the cylinder body on the side of one of the working chambers so as to fit around the working shaft to divide one working chamber. A hydraulic operation circuit comprising a fixing means operated by a pressure liquid provided in the cylinder body of a pressure cylinder so that the operation of the piston can be fixed freely, and a hydraulic circuit provided so that the free piston can be operated independently with respect to the piston. .
