    • A mounting member (5) fixed to an engine and a mounting member (1) fixed to a vehicle body are interconnected by a hollow elastomeric block (2) which has a variable-volume primary fluid chamber (13) defined therein. A subsidiary fluid chamber (7) having a diaphragm (4) on a portion of an outer wall (5) thereof communicates with the primary fluid chamber (13) through two fluid passages (21,22). A movable plate (12) forming a portion of the outer wall (8) of the primary fluid chamber (13) is connected to a voice coil motor (14), and by one example, is driven at the same phase as a vibration applied from the engine. During a normal traveling, both the fluid chambers (13,7) communicate with each other through the fluid passage (21,22) having a smaller length. During idling or during a low speed traveling, a switch-over valve (20) is operated to permit both the fluid chamber to be put into communication with each other through the fluid passage (21,22) having a larger length. With the above construction, it is possible to stably exhibit the performance of the vibration-isolating mount device (M) in a wide frequency region.
