A fluid-filled cylindrical elastic mount having an inner sleeve and an outer sleeve, and an elastic body interposed therebetween. The elastic mount also has a intermediate sleeve having a plurality of windows through which a plurality of pockets formed at respective circumferential positions of the elastic body are open in the outer circumferential surface of the intermediate sleeve, respectively. The plurality of windows are fluid-tightly closed by the outer sleeve, thereby defining a plurality of fluid chambers filled with a non-compressible fluid. The elastic mount further includes an orifice member for defining an orifice passage for fluid communication between the plurality of fluid chambers. The orifice member disposed in at lest one of the plurality of windows such that the orifice member circumferentially extends over the entire circumferential length of said at least one window, and that the orifice member has its axial length which varies in its circumferential direction such that the orifice member is held in abutting contact with the axially opposite edges of said at least one window in the circumferentially intermediate portion of the window, while being axially spaced apart from the axially opposite edges of the window in at least circumferentially opposite end portions of the window, so as to provide opening through which the corresponding pocket is open in the outer circumferential surface of the intermediate sleeve. The method of producing the mount is also disclosed.
