ABSTRACT:
A fluid-filled elastic mounting structure including a first and a second support member, an elastic body for elastically connecting the first and second support members, a closure member which partially defines a fluid chamber, a partition assembly for dividing the fluid chamber into a pressure-receiving chamber and an equilibrium chamber, and at least one orifice for fluid communication between the pressure-receiving chamber and the equilibrium chamber. The first support member includes a hollow cylindrical member extending in a direction perpendicular to the load-receiving direction. The mounting structure of the invention further includes a stopper member which is formed from a plate-like member and secured to said second support member, so as to extend from the second support member toward the first support member, and surround the first support member such that the hollow cylindrical member is spaced apart from the stopper member by a suitable distance. This stopper member serves to limit an amount of relative displacement of the first and second support members away from each other in the load-receiving direction. Further, a rubber layer is provided for covering the stopper member over a substantially entire surface area thereof, the rubber layer being integrally formed with the elastic body.
