PURPOSE:To improve a dumping characteristic in a wide temperature range by using a mixture of an ethylene glycol liquid and a propylene glycol liquid at a ratio of 50/50-75/25 for a fluid filled in a main closed chamber and an auxiliary closed chamber. CONSTITUTION:An anti-oscillation supporter is fixed between an automobile body and an engine with fixtures 2, 3; and the height H of an elastic tube 1 is reduced to H' in accordance with oscillations, thereby and together with the effect of a metal band 20 bound around the elastic tube 1 the volume in a main closed chamber 4 is reduced, accordingly the fluid filled inside it moves into an auxiliary closed chamber 6 through a vent hole 7 provided on a partition wall 3' for dumping action. By using a mixture of an ethylene glycon liquid and a propylene glycol liquid at a ratio of 50/50-75/25 for this filled fluid, an excellent anti-oscillation action can be attained at a high or a low temperature. |
