A fluid-filled resilient bushing including a resilient member interposed between inner and outer sleeves, and an elastically yieldable partition member. The resilient member and the partition member cooperate with a sealing sleeve to define a pressure-receiving chamber and an equilibrium chamber, which are disposed opposite to each other in a first direction in which the bushing receives a vibrational load. The chambers communicate with each other through an orifice. The bushing includes a stopper block which has a stopper portion disposed within the pressure-receiving chamber, so as to extend in the radial direction. The stopper portion has a radial end face whose periphery is spaced apart from the periphery of the pressure-receiving chamber. A damping member is fixedly provided on the radial end face of the stopper portion. The peripheral portion of the restrictor member projects from the periphery of the radial end face of the stopper portion, such that an annular gap is formed between the peripheral portion and the periphery of the pressure-receiving chamber. This annular gap serves to isolate high-frequency vibrations.
