Abstract
In a liquid-filled anti-vibration mounting device suitable such as for an engine mount, an accommodation room containing a rubber movable plate is formed inside a partition member partitioning a liquid chamber into a pressure receiving chamber and a balancing chamber. The partition member includes a pair of division walls, one adjoining the pressure receiving chamber and the other adjoining the balancing chamber. Each division wall is formed with a plurality of communication holes. The communication holes are arranged to undulate at least a portion of the movable plate towards the peripheral edge thereof at specified circumferential intervals or greater by the action of the liquid pressure through the communication holes. The movable plate thus deformed, particularly its portion towards the peripheral edge, has a small area to come into contact with the division walls at a time, which effectively disperses and lessens a shock due to contact.
