LIQUID-SEALED VIBRATION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an engine mount capable of restraining the transmission to the casing side by smoothly absorbing impulsive vibration by cavitation by an elastic member. SOLUTION: This vibration control device floatingly supports a contact part 39 of an outer peripheral edge part of an orifice member 36 partitioned into a pressure receiving chamber 37 and a balancing chamber 38 in a casing 10 of the engine mount 1, without being restricted in a state of sandwitching both upper-lower surfaces between a pressure receiving chamber side thick elastic body 41 thickly projected downward from an under surface outer peripheral edge part of a body rubber-like elastic body 4 in an outer peripheral edge part inner surface of the body rubber-like elastic body 4 exposed to the pressure receiving chamber 37 side and a balancing chamber side thick elastic body 342 thickly projected upward from an outer peripheral edge part of a diaphragm member 34 in the outer peripheral edge part inner surface of the body rubber-like elastic body 4 exposed to the balancing chamber 38 side.
