を設けたことを特徴とする油圧緩衝器。 A wheel-side tube is slidably inserted into the vehicle-side tube, a hollow piston rod is movably inserted into the wheel-side tube via a bearing and a piston, the piston rod is connected to the vehicle-side tube, and the piston is inserted into the wheel-side tube. The inside is divided into a rod side chamber and an anti-rod side chamber, and the two chambers form an expansion port and a pressure port provided on the piston, and an expansion valve and a pressure valve are provided at the outlet end of each port, respectively, so that they can be opened and closed. In a hydraulic shock absorber forming a reservoir between the piston rod and the piston rod, a passage is provided in the piston rod, and this passage communicates with the opposite-rod side chamber and the reservoir through a through hole and with the rod side chamber through an orifice. The hydraulic shock absorber is further provided with a check valve that allows oil to flow only from the piston rod internal passage to the opposite rod side chamber in the middle of a through hole that communicates the passage in the piston rod with the opposite side chamber.
