とする液圧′　　　　　機構。A hydraulic mechanism comprising a hydraulic pressure generating device having a cylinder body and a piston, an actuator driven by pressure fluid obtained from the hydraulic pressure generating device, and an actuating member for operating the hydraulic pressure generating device. By dividing the piston inserted into the cylinder body into two, the hydraulic pressure chamber is divided into a first hydraulic pressure chamber and a second hydraulic pressure chamber, and the movement of each piston is controlled on the inner wall of the cylinder body. A stopper is provided to regulate the pressure fluid, and the pressure fluid led out from the first and second hydraulic pressure chambers is connected to the actuator side through piping, and a piston is connected to the pressure fluid generation port of the first hydraulic pressure chamber located on the operating member side A check valve is provided that opens and closes by the reciprocating action of the
A hydraulic mechanism characterized by being equipped with an orifice that regulates the final stage flow rate of return pressure fluid from the actuator side when the check valve is opened.
