けるオイルロツク構造。 The inner tube is slidably inserted into the outer tube, and a cylinder filled with hydraulic oil for generating damping force and whose end is closed with an oil seal case is installed, and a hollow rod is inserted into the inner tube. In a hydraulic shock absorber, the end of the hollow rod is fixed to an oil lock piece fixed to the bottom cap, and an oil reservoir filled with lubricating oil is formed at the bottom of the inner tube and inside the bottom cap, A check valve for opening and closing the oil passage in the hollow rod is provided on the inner circumference of the oil lock piece, and a check valve is formed when the oil seal case is fitted between the bottom cap and the oil lock piece while maintaining a clearance. The oil seal case, the hollow rod, and the oil lock piece are provided with oil holes so as to communicate the upper oil reservoir and the lower oil reservoir through the oil passage of the hollow rod. Oil lock structure in buffer.
