Abstract
A fluid-filled elastic mount wherein an elastic body elastically connecting a first and a second support partially defines a fluid chamber filled with a non-compressible fluid. The elastic mount further includes an oscillating plate which partially defines the fluid chamber and which is supported by the second support such that the oscillating plate is displaceable relative to the second support, and an electrostrictive/magnetostrictive element for oscillating the oscillating plate to thereby change a pressure of the fluid in the fluid chamber. The second support has a small-diameter cylindrical portion to which the elastic body is secured, and a large-diameter cylindrical portion in which the oscillating plate having a large surface area is accommodated. The electrostrictive/magnetostrictive element is interposed between the oscillating plate and a support member fixed to the second support.
