<p><P>PROBLEM TO BE SOLVED: To contribute to an ecologically ideal operation or the like of an engine by accurately resolving offset shifting and stroke-range fluctuation of an actuator without enlarging a device. <P>SOLUTION: In an antivibration device 1, a liquid-sealed part 2 having a pressure receiving chamber 24 sealed with antifreezing fluid F that is a non-compressible fluid between a mount rubber 22 that is a rubber elastic body and a movable film 23 which are opposed to each other, to which an attachment portion 25 that is an input end for transmitting vibration of an excitation source to the mount rubber 22 is connected, is assembled to an actuator 3 for moving forward and backward a movable element 5 arranged in an operation space S1 so as to operate the movable film 23 by the forward/backward movement of the movable element 5, whereby a vibration input from the attachment portion 25 to the liquid-sealed part 2 is controlled. Oil L that is a liquid pushing member for reducing the existing amount of air in a communicating space S is introduced to any portion of the communicating space S which includes the operation space S1 and is in a mutually communicating state therewith. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
