<P>PROBLEM TO BE SOLVED: To exert attenuation characteristics against vibration along both directions of an axial direction and a radial direction while achieving compactification, simplification in structure, and simplification in manufacture. <P>SOLUTION: A vibration-proofing system 1 includes: a first attachment member 2 of cylindrical form and a second attachment member 3; a first elastic body 4 that connects both the attachment members 2, 3; a first partition wall 10 that comparts a liquid chamber 5 in the first attachment member 2 in the axis O direction to define a main liquid chamber 8 and a sub liquid chamber 9; a second partition wall 12 that circumferentially comparts the main liquid chamber 8 to define a plurality of split main liquid chambers 11; and a plurality of limit paths 35 that make the plurality of split main liquid chambers 11 communicate with the sub liquid chamber 9 individually. A part of the first partition wall 10 is configured by a second elastic body 26; and each of the split main liquid chambers 11 is formed to be different in the amount of change in volume that increases or decreases by elastic deformation of the first elastic body 4 and the amount of change in volume that increases or decreases by elastic deformation of the second elastic body 26 when a load is applied to the vibration-proofing system 1 in the axis O direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
