Title: Fluid-filled vibration damping device and method of manufacturing the same

Abstract: Disclosed is a fluid-filled vibration-damping device and a method of manufacturing the same, wherein an elastic body connecting a first and second mounting members partially defines a fluid-filled zone filled with non-compressible fluid, and a sealing part of the fluid-filled zone is formed by forcedly fitting an annular fixing projection formed on one of an inner circumferential surface of a first sealing member or an outer circumferential surface of a second mounting member into an annular fixing recess formed onto the other. Drain passages are formed at an interface between the annular fixing recess and projection to expose a floor of the annular fixing recess to an outside. Compressed air is blown into one of the drain passages so as to blow away or forcedly discharge the non-compressible fluid remained on the floor of the annular fixing recess to the outside through another drain passage.
