PURPOSE:To provide a liquid-sealed type vibration-proof device which can vibrate a diaphragm with efficiency and surely absorb vibration of high frequency. CONSTITUTION:An auxiliary liquid chamber 44 is connected to a pressure liquid chamber 42 through a limiting passage 56. A disk state diaphragm 38 is provided as a part of a partition wall of the pressure liquid chamber 42 supported by an elastic supporting body 40 such as a rubber. On the side of the diaphragm 38 opposite to the pressure liquid chamber 42, an electromagnetic solenoid 70 is provided, and a driving shaft 70A is connected to the diaphragm 38. A compression coil spring 78 is provided between the diaphragm 38 and an electromagnetic solenoid body 70B. When the diaphragm 38 is moved in the direction separating from the electromagnetic solenoid 70, as it is moved by an energizing force of the compression coil spring 78, the diaphragm can be vibrated with efficiency to a zone of a high frequency. |
