PROBLEM TO BE SOLVED: To restrict occurrence of cavitation in encapsulated working fluid in an adaptive hydraulic type vibration-proofing device and prevent occurrence of irregular noise or shock accompanied by collapse of cavitation.SOLUTION: This invention provides liquid composition for vibration-proofing device including annular chemical compound (A) expressed by the following general formula (1) (in the general formula (1), X denotes a kind of functional group of any of ester group, carbonate group, N-substituted alkyl amide group, N,N'-disubstituted alkyl urea group, sulfoxide group, and R denotes hydrogen atom or methyl group. (m) and (n) denote natural number selected in such a way that m+n becomes a value ranging 2 to 6. |
