The vibration transmitter is provided with a cavity having a substantially constant gap therein which is substantially perpendicular to the vibration transmission direction, and
a partitioning mechanism in which a partition wall defining the void space is provided with a through hole for communicating the void space with the equilibrium chamber and the pressure receiving chamber; A fluid-filled type including a rubber elastic plate of a predetermined thickness that is provided so that the rubber elastic body can be easily elastically deformed by moving the rubber elastic plate in the vibration transmission direction. In the anti-vibration support, a predetermined buffer protrusion is formed on at least one surface of the rubber elastic plate, and the shock generated when the rubber elastic plate abuts against the partition wall of the cavity is absorbed by the elastic deformation action of the buffer protrusion. A fluid-filled vibration-proof support body characterized by being designed to reduce vibrations.
