PROBLEM TO BE SOLVED: To easily maintain performance of an electric body over a long period.SOLUTION: In a vibration isolator 10, a plurality of pressure receiving liquid chambers 25, 26 in which a part of each wall surface is constituted of an elastic body 14 are arranged in a first attachment member 12, and the pressure receiving liquid chambers 25, 26 include a pair of first pressure receiving liquid chambers 25 mutually connected through a first restriction passage 27 and the second pressure receiving liquid chamber 26 connected to a sub liquid chamber 28 through a second restriction passage. The pair of first pressure receiving liquid chambers 25 are arranged so as to insert the second attachment member 13 between them, the second pressure receiving liquid chamber 26 is arranged in parallel with the second attachment member 13 in an orthogonal direction D1 orthogonal to both directions, i.e., an axial direction of the first attachment member 12 and an insertion direction D2 for inserting the second attachment member 13 between the pair of first pressure receiving liquid chambers 25, the second attachment member 13 is extended over the whole lengths of respective axial directions of the pair of first pressure receiving liquid chambers 25 and the second pressure receiving liquid chamber 26, and the first restriction passage 27 is formed so as to avoid the sub liquid chamber 28. |
