PURPOSE:To improve vehicle maneuvering stability and vibration-proofing performance by interposing a rubber elastic body between a mount fitting and a support fitting, integrally connecting both fittings to each other on the other hand, forming a fluid chamber between both fittings, and fixedly supporting an action member inside the fluid chamber on either one fitting side. CONSTITUTION:A mount fitting 10 and a support fitting 26 are elastically connected to each other by means of inner and outer rubber elastic bodies 28 and 30, and a coil spring is elastically supported on a body side via the inner and outer rubber elastic bodies 28 and 30. When the elastic bodies 28 and 30 are deformed with a body load inputted from a coil spring under this mounting condition, a fluid chamber 42 is deformed, an action block 44 arranged inside the fluid chamber 42 is positioned at the approximate center part of the fluid chamber 42, and as a result, the inside of the fluid chamber 42 is narrowed with the action block 44, and a vibration action part having a given gap is formed between the outer surface of the action block 44 and the inner surface of the fluid chamber 42. When vibration input exists between both fittings 10 and 26, flow or resonance of fluid occurs within above mentioned vibration action part. |
