り付けたことを特徴とする油圧緩衝器。(1) The inside of the cylinder is divided into two oil chambers by a piston with a damping valve, and the cylinder has the above-mentioned piston at one end, and damps when the piston rod moves in and out of one sealed end of the cylinder and the cylinder moves relative to each other. In a hydraulic shock absorber configured to generate force, a ring groove of a predetermined axial length is provided on the outer circumference of the piston, and a piston ring that is slidable in the axial direction with respect to the ring groove and the inner circumference of the cylinder is provided within the ring groove. In the ring groove, a cut groove is formed in which the groove width or groove depth gradually decreases from the center to both ends, and a buffer ring is attached to both ends of the ring groove. Features a hydraulic shock absorber.
の範囲第１項記載の油圧緩衝器。(2) The hydraulic shock absorber according to claim 1, in which the depth of the cut groove changes in an arc shape.
範囲第１項に記載の油圧緩衝器。(3) The hydraulic shock absorber according to claim 1, in which the width of the kerf changes in an arc shape.
