An engine mount device is described comprising: an annular elastic block having inner and outer peripheral sections one of which is connected to a power unit side and the other connected to a support body side; a partition plate; an annular elastic member connected directly to and extending between the elastic block and the partition plate; the partition plate member connected to and elastically supported by the annular elastic member, the partition plate member being formed with an orifice and defining between it and the elastic block a fluid chamber at least a part of which is capable of being filled with a fluid; and a diaphragm member connected with the partition plate member and defining between it and the partition plate member an auxiliary chamber at least a part of which is capable of being filled with the fluid. The auxiliary chamber is in communication with the fluid chamber through the partition plate member orifice. The peripheral edges of the partition plate are elastically supported by the annular elastic member and thereby movable relative to the elastic block in upward and downward directions in response to deformation of the annular elastic member.
