レータ。[Claims for Utility Model Registration] (1) The structure is formed so that the hydraulic oil flowing out from the hydraulic shock absorber main body when the lock valve is activated flows into the accumulator, thereby preventing the hydraulic shock absorber main body from operating. In an accumulator in a hydraulic shock absorber, a free piston that partitions an oil chamber and a gas chamber in the accumulator main body has a protrusion formed on the oil chamber side end surface thereof to have a pressure receiving surface at its tip, and A guide hole into which the protrusion can be inserted is formed on the oil chamber side end surface of the accumulator body, which the tip of the protrusion faces.
An accumulator in a hydraulic shock absorber, characterized in that the guide hole is communicated with the inside of the hydraulic shock absorber main body. (2) The accumulator in the hydraulic shock absorber according to claim 1, wherein the lock valve is disposed in a passageway that allows communication between an upper chamber and a lower chamber in the hydraulic shock absorber main body. (3) The accumulator in the hydraulic shock absorber according to claim 1, wherein the oil chamber within the accumulator is communicated with the upper chamber within the hydraulic shock absorber main body.
