VIBRATION ISOLATOR

Japanese Patent JP2017214960

A

PROBLEM TO BE SOLVED: To provide a vibration isolator capable of restricting the occurrence of cracks on a partition wall.SOLUTION: A vibration isolator comprises: a cylindrical first fitting component 10 and a second fitting component 20 disposed radially inward of the first fitting component 10; an elastic body 30 connecting the first fitting component 10 to the second fitting component 20; and a partition member 40 for partitioning the liquid chamber 70 in the first fitting component 10 into a main liquid chamber 71 and a sub liquid chamber 72, the elastic body 30 serving as a part of the partition wall. The partition member 40 is provided with an elastic plate 41 which is arranged to face the elastic body 30 in the axial direction and constitutes a part of the partition wall of the main liquid chamber 71; the elastic plate 41 is formed with a partition wall 41a which projects toward the elastic body 30 and partitions the main liquid chamber 71 into a first main liquid chamber 71a and a second main liquid chamber 71b; and the partition member 40 is provided with a first orifice passage 42a for communicating the first main liquid chamber 71a and the sub liquid chamber 72, and a second orifice passage 42b for communicating the second main liquid chamber 71b and the sub liquid chamber 72.SELECTED DRAWING: Figure 1
