PROBLEM TO BE SOLVED: To provide an engine mount 10 capable of inhibiting cavitation while achieving low cost and saving space. SOLUTION: This engine mount includes an inner tube member 16 connected to an engine, an outer tube member 14 connected to a vehicle body 16, an elastic body 18 elastically supporting the inner tube member 16 and the outer tube member 14, an orifice passage 114 providing communication between a main liquid chamber 84 and an auxiliary liquid chamber 86, a membrane member 75 deforming according to pressure difference between the main liquid chamber 84 and the auxiliary liquid chamber 86, and a coil spring 140 urging the membrane member 75 toward the auxiliary liquid chamber 86 from the main liquid chamber 84. The coil spring 140 is formed so as to surface the membrane member 75 and provide communication between the main liquid chamber 84 and the auxiliary liquid chamber 86 if pressure of the main liquid chamber 84 is not greater than a predetermined value.
