Abstract

PURPOSE: To provide a titled composition without forming a precipitated substance by incorporating a dialkyl dithiophosphate or the like, a long-chain aliphatic acid or the like, a long-chain aliphatic acid or the like and a detergent dispersant as essential components to a hydrocarbon base luburicating oil as a base oil.
CONSTITUTION: A hydraulic fluid composition for a damper contains a hydrocarbon base luburicating oil as a base oil and contains (A) 0.1W3.0wt% a zinc dialkyl or diaryl dithiophosphate, (B) 0.05W7.0wt% one or more of an oiliness improver selected from long-chain alphatic acids or alkyl esters thereof or oils and fats, and (C) 0.1W 5.0wt% detergent dispersant. Herein, as an alkyl group of (A), 3W12C alkyl, as an aryl group, 6W15C phenyl or alkylphenyl is preferred. As (B), palmitic acid, stearic acid, soybean oil or the like are mentioned and, as (C), an alkaline earth metal salt of petroleum sulphonic acid or alkylsalicylic acid is used.
