ABSTRACT:
A fluid-filled mount having first and second elastic bodies which elastically connect an inner and an outer sleeve and partially define a pressure-receiving chamber which communicates with a variable-volume equilibrium chamber through an orifice passage. The first elastic body includes two radial portions extending from diametrically opposite circumferential portions of the inner sleeve, in respective radial directions almost perpendicular to a diametric direction in which a static load acts on the mount. A connecting member extends from the inner sleeve between the above two radial portions and which is located on one of diametrically opposite sides of the inner sleeve on which the radial distance between the two sleeves is reduced by the static load. The second elastic body includes two thin-walled lateral walls which extend from respective axially opposite ends of the connecting member and which are inclined in a radially outward direction of the mount, and further includes two thick-walled radial walls which extend from the ends of the lateral walls in the above diametric direction.
