ルブ機構。 In a hydraulic shock absorber, a piston is slidably disposed in a cylinder, and an oil passage and a two-stage valve mechanism for opening and closing the oil passage are provided on the piston to generate damping force. The first stage valve and the second stage valve are separated by a distance piece interposed between the two valves, and a bypass oil passage is formed to bypass the first stage valve. A valve mechanism for a hydraulic shock absorber characterized by being provided with a select valve that opens and closes a bypass oil passage.
