A fluid-filled vibration device including a pressure receiving chamber and an equilibrium chamber communicated by an orifice passage and a connecting hole provided on a partition member partitioning the two chambers. The connecting hole is closed by a closing rubber elastic plate to which pressures of the two chambers are applied from the respective sides. The closing rubber elastic plate includes at its outer circumference edge part abutting retaining parts held by the partition member, an elastic deformation area which is provided circumferentially between the abutting retaining parts and elastically deformed to open the connecting hole, and a mass part provided at a circumference direction intermediate part of the elastic deformation area to constitute a mass-spring system together. The resonance frequency of the system is tuned to 50 Hz or greater and set higher than a tuning frequency of the orifice passage.
