In a hydraulic shock absorber that forms a chamber,
A sub-tank is provided on the outside of the one tube, a free piston is slidably fitted in the sub-tank, high-pressure gas is sealed in the back of the free piston, and the oil reservoir chamber is communicated with the sub-tank. Further, a throttling means and a check valve are interposed in the flow path of the oil reservoir chamber communicating with the gas chamber of the shock absorber body, and the check valve opens when the shock absorber is extended to open or bypass the throttling means. Hydraulic shock absorber anti-dive mechanism. (2) The anti-dive mechanism for a hydraulic shock absorber according to claim 1, wherein an orifice is formed in the check valve.
