To provide a liquid-encapsulated engine mount of hangdown type as improvement of a conventional technique involving such a problem that a liquid column resonance occurs when a high-frequency vibratory input is applied in the fore-and-aft direction while any vehicle is in an accelerative running, etc., to lead to heightening of the dynamic spring constant, which allows the vibration from the engine to be transmitted to the wall of the cabin to result in generation of the acceleration noise.

The liquid-encapsulated engine mount of hangdown type is composed of an outer metal piece 17, an inner metal piece 18, a supporting rubber part 20, a main liquid chamber 48 and auxiliary liquid chamber 50, a partitioning member 14 to partition them from each other, and an orifice passage 54 in the circumferential direction to put the two chambers 48 and 50 in mutual communication, wherein a front-rear separation wall 66 is installed extending in the left-right direction inside the main liquid chamber 48 using the vehicle fore-and-aft direction as the reference for partitioning the main liquid chamber 48 into a front chamber 68 and a rear chamber 70, and a communication passage 72 is provided for putting the two chambers 68 and 70 in mutual communication in the direction fore and aft.
