タリング防止装置。 An oil stopper in which two disc valves with multiple oil holes are connected at regular intervals around the periphery, a piston rod is fixed to one of the disc valves, and a tapered hole and multiple oil holes are opened and closed at the center of the other disc valve. The oil damper piston rod is provided with a ring and a stopper for the oil stop ring, and a damping force adjustment bolt whose tip is tapered so as to fit into the taper hole facing the cylinder surrounding the disc valve is fixed with a lock nut. A check valve chattering prevention device characterized by being linked to a valve body of the stop valve so that movement of the valve body is transmitted to an oil damper.
