ABSTRACT:
A fluid-filled engine mount device comprises first and second base plate members which are connected to a power unit side and a vehicle body side, respectively; a block made of elastic material and interposed between the first and second base plate members, the elastic block being formed with a cavity; a partition plate member having an orifice, located in the vicinity of and spaced from the first base plate member to define a fluid chamber to be filled with a fluid and an auxiliary chamber which communicates with the fluid chamber through the orifice; and an elastic support member for connecting the partition plate member with the first base plate member, includes a secured section secured to the first base plate member, and an annular section located inside of the inner wall surface of the elastic block cavity and inside of the first base plate member in the radial direction, and located between the secured section and the partition plate member peripheral section, thereby effectively preventing high frequency vibration from being transmitted to the vehicle body side, achieving an effective damping of total vibrations applied to the engine mount.
