PURPOSE:To secure a low-motion spring characteristic in relation to vibration in a relatively high-frequency area subject to a close noise. CONSTITUTION:A cylinder part 11 consisting of a ringlike projection is installed at the side, namely, in the lower part of an insulator 1 consisting of vibro- isolating rubber and faced to a main chamber 7. This cylinder part 11 is integrally formed with the same member as the insulator 1. A hat profile-form projection 41 is installed in the central part of a partition plate 4. This projection 41 is inserted into the cylinder part 11. In succession, a clearance is installed in space between an inner wall of this cylinder part 11 and an outer wall of the projection 41, making this clearance turn to a passage 77. With this passage 77, the main chamber 7 is divided into a first liquid chamber 71 and a second liquid chamber 72, and further an interval between these first and second liquid chambers 71 and 72 interconnected freely via this passage 77. |
