ABSTRACT:
A fluid-filled cylindrical elastic mount, including: a center shaft member; an intermediate sleeve; an elastic body; an outer cylindrical member having a thin sealing rubber layer on its inner circumferential surface and inserted on the sleeve; fluid chambers; and an outward flange provided at a first axial end of the mount. The outer cylindrical member has a concave portion, and the sleeve has a cylindrical portion at its one end located on the side of the first axial end and corresponding to the one end of the outer cylindrical member. An end face of the cylindrical portion of the sleeve is located nearer to a second axial end of the mount which is axially opposite to the first axial end, than a smallest-inside-diameter portion of the concave portion, whereby the end face of the cylindrical portion axially engages the engaging protruding portion of the sealing rubber layer.
