したことを特徴とする油圧緩衝器。In a hydraulic shock absorber, a rod-shaped valve guide is disposed as a valve that performs a damping effect by circulating oil, and a flat valve body having a fitting hole that slides into the valve guide is provided. A concave groove is provided in the outer peripheral surface of the valve guide in which the flat valve body fits into the sliding tube in the direction of opening and closing movement of the valve body, and this concave groove is used as an orifice through which oil flows. Hydraulic buffer.
