(57) [Abstract] [Purpose] It shows good friction characteristics under conditions where slight vibrations and amplitudes are applied to the shock absorber, and also when used in shock absorbers using polyterorafluoroethylene resin members. , To provide a hydraulic fluid composition for shock absorbers exhibiting sufficient wear resistance and friction characteristics. A hydraulic fluid composition for a buffer, comprising a base oil, at least one compound selected from the group consisting of phosphoric acid esters, phosphorous acid esters and phosphoric acid ester amine salts, and an alkanolamine. .. |
