<p><P>PROBLEM TO BE SOLVED: To effectively absorb input vibration by vibration of a movable plate arranged in a partitioning member for partitioning a main liquid chamber and an auxiliary liquid chamber from each other and prevent occurrence of abnormal sound due to collision of the movable plate and the partitioning member when inputting vibration having predetermined frequency. <P>SOLUTION: Central points of a plurality of slot openings in a bottom plate part 74 of the vibration control device 10 and central points of a plurality of slot openings 90 in a top plate part 77 are eccentric on the opposite side using a shaft axis S as the center. Consequently, when liquid pressure in the main liquid chamber 56 rises above liquid pressure in the auxiliary liquid chamber 58 when inputting vibration, the movable plate 92 causes such inclination that makes an interval from a part on one end side in the radial direction to the top plate part 77 narrow relatively and makes an interval from a part on the other end side in the radial direction to the top plate part 77 wide relatively to reduce hitting sound caused when the movable plate 92 is abutted on the bottom plate part 74. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
