とを特徴とする油圧緩衝器。 An inner cylinder is provided inside the outer cylinder, a piston is fitted into the inner cylinder, and a piston rod to which the piston is fixed is slidably supported by a rod guide attached to the upper end of the inner cylinder. In addition, in a hydraulic shock absorber equipped with an oil seal that liquid-tightly separates the inside and outside of the outer cylinder above the rod guide, the outer periphery of the upper surface of the reinforcing ring, which is the core material of the oil seal, is The reinforcing ring is formed into a raised concave cross-sectional shape, is placed on the guide, and the upper end of the outer cylinder is caulked from the outer periphery of the reinforcing ring toward the upper surface, so that the reinforcing ring is connected to the caulked portion and the rod guide. At the same time, a passage is provided between the rod guide and the reinforcing ring to communicate the inner circumferential side and the outer circumferential side, and a check clip is provided on the outer circumferential side of the passage to allow flow only from the inner circumferential side to the outer circumferential side. A hydraulic shock absorber characterized by being equipped with.
