A fluid-filled vibration damping device including: a pressure-receiving chamber; an equilibrium chamber; a partition partitioning the two chambers while including a communication aperture connecting the two chambers; and a rubber elastic plate arranged in the partition while covering the communication aperture. The rubber elastic plate includes: an outside contact-retainer part provided partially along a circumference at an outer edge of the rubber elastic plate while being held overlapped with the partition; an elastic deformation zone provided circumferentially between the outside contact-retainer part to become apart from the partition based on a pressure differential between the two chambers thereby allowing a fluid flow through the communication aperture; and a radial reinforcing rib projecting from a surface of the rubber elastic plate and extending radially outward from an inside contact-retainer part that is held overlapped with the partition toward the elastic deformation zone.
