PROBLEM TO BE SOLVED: To provide a simply configured low cost vibration isolator.SOLUTION: A vibration isolator includes a first limit passage 51 and a second limit passage 52. The first limit passage 51 includes pressure loss units 53a, 53b. The pressure loss units 53a, 53b are provided with an intermediate chamber 55, a first communication passage 57, and a second communication passage, respectively. An aperture axis of a first aperture 59 opening into the intermediate chamber 55 in the first communication passage 57 is displaced relative to an aperture axis of a second aperture opening into the intermediate chamber 55 in the second communication passage. At least one of the first aperture 59 and second aperture opens toward a wall surface defining an intermediate chamber 55. The vibration isolator includes a first pressure loss unit 53a as the pressure loss unit 53a, 53b, where the first communication passage 57 directly communicates with a first liquid chamber 14 and the first aperture 59 opens toward the wall surface defining the intermediate chamber 55. A part of the wall surface facing the first aperture 59 is formed of an elastic membrane 39, the wall surface defining the intermediate chamber 55 in the first pressure loss unit 53a. |
