PURPOSE: To effectively develop the function of a throttle flow passage by allowing a foamed body having independent gas foams built in to prevent the obstruction for the flow of the sealed liquid in the throttle flow passage, as for a liquid seal type vibration controller which has the foamed body which possesses the dynamic spring constant adjusting function. CONSTITUTION: A main liquid chamber A having a thick rubber elastic body 1 as chamber wall and a subliquid chamber B having a thin rubber film 2 as chamber wall are divided by a partitioning plate 3, and both the liquid chambers A and B are allowed to communicate through a throttle flow passage 4. A projection part 31 is formed on the partitioning plate 3 faced to the main liquid chamber A, and a foamed body 8 which encloses a number of independent gas foams is fitted with the projection part 31. Further, the top end part of the projection part 31 is formed to the large diameter, and formed to a stopper 32, and the slip-off of the foamed body 8 is prevented. |
