Abstract

PURPOSE:To produce an excellent vibration isolating effect against input vibration in a wide frequency area, by a method wherein a second moving means, absorbing a difference in a fluid pressure between first and second division chambers is mounted to a second partition member, forming an annular throttled part, so that it is deformable and displaceable by a given amount. CONSTITUTION:A thin section part 62 is formed to a bottom 57 of a second partition member 56. When a difference in a fluid pressure between first and second division chambers 58 and 60 is produced, the thin section is deformed by a given amount, and based on liquid column resonance phenomenon occasioned by deformation of the thin section part 62, input vibration in a frequency area set to the thin section part 62 is effectively shut off. An annular bottleneck part 70 to divide the second division chamber 60 into approximately two parts of chamber parts 66 and 68 is formed. When a difference in a fluid pressure between the two parts 66 and 68 is produced, fluids in the two chamber parts flow to the opposing chamber part through the bottleneck part 70. Based on the liquid column resonance action of noncompressive fluid, input vibration in a frequency area set to the bottleneck part is effectively shut out. This constitution enables provision of an excellent vibration isolating effect against input vibration in a frequency area wider than a conventional means.
