A vibration isolator comprising a partition member including a plurality of communicating holes (27a, 27b) extending outward in an axial direction of the vibration isolator from a portion (18a, 18b) of a wall surface of an accommodating chamber, the portion of the wall surface facing a movable member, the plurality of communicating holes (27a, 27b) being configured to communicate the accommodating chamber with a main liquid chamber or a subsidiary liquid chamber, and at least one of the plurality of communicating holes (27a, 27b) being a direct coupling hole configured to directly couple the accommodating chamber with the main liquid chamber or the subsidiary liquid chamber in the axial direction, the vibration isolator further comprising: a first tubular attachment member coupled to one of a vibration-generating part and a vibration-receiving part and a second attachment member coupled to the other part; an elastic body configured to couple the attachment members (11, 12) to each other; the partition member configured to divide a liquid chamber in the first attachment member in which a liquid is sealed into the main liquid chamber having the elastic body as a portion of a wall surface and the subsidiary liquid chamber; and the movable member accommodated in the accommodating chamber provided at the partition member deformably or displaceably in the axial direction of the first attachment member; and a flow control member positioned closer to an outside in the axial direction than the direct coupling hole and disposed to overlap the movable member in the axial direction through the direct coupling hole, wherein the flow control member does not come into contact with the movable member deformed or displaced in the axial direction when a liquid pressure of the main liquid chamber varies based on an input from the vibration-generating part, characterised in that the movable member includes an exposed area, in which the movable member is exposed to the main liquid chamber or the subsidiary liquid chamber by the direct coupling hole, a part of the exposed area overlapping a portion of the flow control member in the axial direction. a first tubular attachment member coupled to one of a vibration-generating part and a vibration-receiving part and a second attachment member coupled to the other part; an elastic body configured to couple the attachment members (11, 12) to each other; the partition member configured to divide a liquid chamber in the first attachment member in which a liquid is sealed into the main liquid chamber having the elastic body as a portion of a wall surface and the subsidiary liquid chamber; and the movable member accommodated in the accommodating chamber provided at the partition member deformably or displaceably in the axial direction of the first attachment member; and a flow control member positioned closer to an outside in the axial direction than the direct coupling hole and disposed to overlap the movable member in the axial direction through the direct coupling hole, wherein the flow control member does not come into contact with the movable member deformed or displaced in the axial direction when a liquid pressure of the main liquid chamber varies based on an input from the vibration-generating part, characterised in that the movable member includes an exposed area, in which the movable member is exposed to the main liquid chamber or the subsidiary liquid chamber by the direct coupling hole, a part of the exposed area overlapping a portion of the flow control member in the axial direction.
