Claims

[Scope of utility model registration request]

A cylinder has a port that is connected to the suction port of a hydraulic pump and is connected via a switching valve to an actuator that is operated by pressure fluid discharged from the hydraulic pump, and a cylinder that has a fluid-tight and sliding structure inside the cylinder. A piston that can be assembled to form a liquid chamber that communicates with the port, and a spring that biases the piston toward the liquid chamber with a predetermined load, and is discharged from the actuator through the switching valve. In the reservoir which accommodates the hydraulic fluid in the fluid chamber and supplies it to the hydraulic pump, a second reservoir is configured to cause the piston to increase or decrease the fluid chamber.
A piston is assembled, and the second piston is actuated prior to the piston by the hydraulic fluid discharged from the actuator and accommodated in the fluid chamber, thereby increasing the fluid chamber. reservoir.
