た弁体を配置したことを特徴とする油圧緩衝器。 It is slidably disposed in a cylinder having an open end, and defines the inside of the cylinder into a first oil chamber on the proximal end side and a second oil chamber on the opening side, and connects these two chambers. In the hydraulic shock absorber, the hydraulic shock absorber includes a piston in which a communicating through hole is formed, and a metering pin that is installed at the base end of the cylinder and that cooperates with the through hole to generate a damping force. A communication passage communicating between the first oil chamber and the outside of the chamber is formed inside the pin, and the communication passage is normally closed, and when the pressure in the first oil chamber exceeds a predetermined pressure. A hydraulic shock absorber characterized by having a valve body that is biased by a spring so as to open.
