置。 A casing in which a cylinder chamber is formed, a piston disposed within the cylinder chamber and reciprocated by pressure oil supplied to the cylinder chamber, and a pressure provided in the casing in communication with the cylinder chamber at a position on the front side of the piston. In a hydraulic actuator comprising a buffer chamber and a flexible air bag inserted into the pressure buffer chamber and having one end open and an opening communicating with the atmosphere, the pressure buffer chamber contains air. an air bag storage chamber into which the bag is inserted; a female threaded section provided adjacent to the inlet side opening of the storage chamber; and an opening to the outside of the casing adjacent to the inlet side opening of the female threaded section. A recessed portion is provided at one end and has a diameter larger than the female threaded portion, and the female threaded portion has a male threaded portion provided at one end, and a recessed portion provided at the other end with a diameter larger than the female threaded portion and smaller than the recessed portion. A hollow holder having a flange portion and a through hole formed in the center is attached by screwing the male screw portion, and an opening of an air bag is connected to one end of the hollow holder. Hydraulic actuated device.
