側減衰力可変機構。 In a hydraulic shock absorber, an inner tube is slidably inserted into an outer tube from below, and is equipped with a piston for generating a damping force that makes sliding contact with the inner peripheral surface of the inner tube. A bypass member is installed on the outer circumferential surface of the outer tube to form a bypass oil passage that communicates with the annular gap between the outer tube and the annular gap through an oil hole formed in the outer tube. It communicates with the upper oil reservoir chamber through the oil hole formed in the outer tube, and a valve holder is installed inside this bypass member, and a needle valve that changes the opening amount of the bypass oil passage is moved back and forth inside this valve holder. A variable damping force mechanism on the rebound side of a hydraulic shock absorber, which is characterized by being freely inserted and inserted.
