ABSTRACT:
A fluid-filled elastic mount having an elastic body which elastically connects a first and a second support member, a closure member which cooperates with the second support member and the elastic body to define a fluid chamber, a partition member which divides the fluid chamber into a pressure-receiving chamber and an equilibrium chamber, and a restrictor passage for restricted fluid communication between the two chambers. The partition member consists of an integrally formed member which has a thin-walled inner portion and a thick-walled outer portion outside of the inner portion. The outer portion has a circumferential groove and is held in pressed contact with the second support member such that the groove is closed so as to define the restrictor passage. The inner portion includes a double-layered structure consisting of a first layer formed of a first elastic material, and a second layer formed of a second elastic material which has a larger modulus of elasticity than the first elastic material. The double-layered structure is elastically deformable due to a difference between pressures in the two chambers.
