Abstract
An engine mount device comprises first and second base plate members; an elastic block securely interposed between the first and second base plate members and formed with a cavity; a partition plate member connected to one of the first and second base plate members and formed with an orifice; a diaphragm member connected to the one of the first and second base plate members and defining an auxiliary chamber between it and the partition plate member, the auxiliary chamber being in communication with the fluid chamber through the partition plate member orifice, at least a part of the fluid and auxiliary chambers being filled with a fluid; and a rigid ring disposed around the intermediate section of the elastic block thereby restricting the expansion of the elastic block; the elastic block and the rigid ring serving as a dynamic damper for damping vibration having predetermined frequencies, thereby rendering unnecessary installing the dynamic damper independent from the engine mount device.
