PROBLEM TO BE SOLVED: To provide a fluid-filled active engine mount of novel structure obtaining active vibration control effect on high frequency vibration, such as booming noise over a wide frequency area, while effectively securing vibration control effect on both low frequency vibration such as shaking using a first orifice passage and medium frequency vibration, such as idling vibration using a second orifice passage. SOLUTION: The first orifice passage 70, which is tuned to low frequency vibration corresponding to shaking and the second orifice passage 90 tuned to medium frequency vibration corresponding to idling vibration, are provided in parallel with each other and independently of an exciting plate 94 displaced excited by an exciting means, and the exciting plate 94 is placed to directly face a pressure-receiving chamber 63. A deformable elastic movable plate 82 is disposed to cover an open part, opened onto the pressure receiving chamber 63 side, of the second orifice passage 90. |
