a cylinder, a piston inserted into the cylinder to partition the cylinder into two compartments, a spring inserted into one compartment to constantly press the piston against one end of the cylinder, and a supply communicating with each compartment; In a hydraulic cylinder device equipped with a hydraulic pump communicating with a discharge port, a flow path is formed inside the piston to communicate each compartment, and
A one-way valve is provided in the flow path where the spring presses only on the side, and the piston is moved within the cylinder against the spring pressure by the rotational drive of the hydraulic pump, and the one-way valve is opened by reversing the hydraulic pump. A hydraulic cylinder device characterized in that the pressure difference in each compartment is set to 0, and the piston is returned to its original position by spring pressure.
