<p><P>PROBLEM TO BE SOLVED: To provide an active fluid filled vibration control device in which developed force by excitation displacement can be increased. <P>SOLUTION: A rib 91 is protruded from an outer circumferential surface of a piston member 9. The rib 91 is extended in the circumferential direction of the piston member 9 and abutted to an inner circumferential surface of an insertion hole 15. Accordingly, during excitation displacement of the piston member 9, fluid pressure is prevented from escaping from a gap between the outer circumferential surface of the piston member 9 and the inner circumferential surface of the insertion hole 15, and the developed force by excitation displacement of the piston member 9 can be increased. As a result, hydraulic control of a first liquid chamber 8a can be performed reliably. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
