PROBLEM TO BE SOLVED: To reduce change of a vibrationproofing effect as much as possible in a specific region of working environmental temperature by reducing change of resistance force by temperature of viscous fluid and by filling specified viscous fluid. SOLUTION: Viscous fluid 1 to fill in an elastic storage body inside 2 is added and mixed with composite powder of a 55-120 weight part of polymethylsilsesquioxan powder and a 1-10 wt.pts. of untreated surface dry type fine powder silica for a 100 wt.pts. of silicon oil so as to adjust variation of resonance multiplying factor from low temperature (-10 deg.C) to a range of high temperature (60 deg.C) small. Additionally, it is added with the composite powder of the 55-120 wt.pts. of polymethylsilsesquioxan powder and the 1-10 wt.pts. of untreated surface dry type fine powder silica against the 100 wt.pts. of silicon oil. Or, composite powder of a 55-120 wt.pts. of polymethylsesquioxan powder and a 1-9 wt.pts. of untreated surface type fine powder silica is added and mixed. |
