<p><P>PROBLEM TO BE SOLVED: To demonstrate the damping characteristic against the vibration along both the axial direction and the radial direction while miniaturizing and simplifying a structure of an antivibration device, and facilitating the manufacture. <P>SOLUTION: An antivibration device 1 includes a first mounting member 2 and a second mounting member 3, a first elastic body 4 for connecting the first and the second mounting members, a partitioning member 10 for demarcating a main liquid chamber 8 and a sub liquid chamber 9 by partitioning a liquid chamber 5 in the first mounting member 2 with the working liquid L being enclosed therein, an elastic partition wall 12 which demarcates the main liquid chamber 8 to form a plurality of divided main liquid chambers 8, and a plurality of limiting passages 35 for respectively communicating the plurality of divided main liquid chamber 8 with the sub liquid chamber 9. The partitioning member 10 has a second elastic body 26 for demarcating the main liquid chamber 8 between the first elastic body 4 and itself, and a rigid part 24 combined with the second elastic body 26 from the sub liquid chamber 9 side along the axial direction O. An elastic partition wall 12 is connected to the second mounting member 3 and the second elastic body 26, respectively. A pressure chamber 40 with the fluid F being enclosed therein is arranged between the second elastic body 26 and the rigid part 24. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
