Abstract
A fluid-filled vibration-damping device includes an elastic body elastically connecting a first and a second mounting member so as to close one open-end portion of the second mounting member, and a partition member assembled with the second mounting member on one side thereof to form therebetween a pressure-receiving chamber partially defined by the elastic body and assembled with a fixing member on the other side thereof to form an equilibrium chamber partially defined by a flexible layer supported by one pen-end portion of the fixing member. The partition member includes a first and second fixing grooves axially spaced apart from each other with an intermediate portion therebetween, to which the other open-end portions of the second mounting and fixing members are respectively press-fitted, and an air passage for connecting a working air chamber to an external air conduit is open in the intermediate portion.
