PURPOSE:To improve a damping effect, by providing a partitioning member, having a throttle passage, in a fluid chamber, partitioned between a load supporting elastic member and an inertia mass unit, in the case of a device which mounts the load supporting elastic member and the inertia mass unit to be interposed between each mounting member in a vibrating body side and a supporting body side. CONSTITUTION:A vibro-isolating supporter, suitable for a power unit of a vehicle, has a mounting member 11 in a car body side and a mounting member 14 in a power unit side. The supporter, mounting a load supporting elastic member 19 of rubber or the like to be interposed between a collar 18 fixed to the upper end of a cylinder 12 in the mounting member 11 and the head part of an anchor bolt 16 in the mounting member 14 while supporting an inertia mass unit 21 to be vertically movably suspended through an elastic material 20 to the peripheral bottom end of the collar 18, partitions a fluid chamber 23 between the unit 21 and the above described elastic member 19. Here the supporter mounts a partitioning member 24, having in its inside a fluidization chamber 25, to be fitted to the internal peripheral bottom end of the collar 18 so as to divide the fluid chamber 23 into two divided chambers 26, 27, while the fluidization chamber 25 floatably houses an orifice plate 28 having a throttle passage 29. |
