VIBRATION ISOLATION DEVICE

摘要

A vibration isolation device (10) of the present invention includes a tubular first attachment member (11) coupled to one of a vibration generating part and a vibration receiving part, and a second attachment member (12) coupled to the other thereof, an elastic body (13) which couples both the attachment members together, and a partition member (16) which partitions a liquid chamber within the first attachment member (11) having a liquid (L) enclosed therein into a first liquid chamber (14) and a second liquid chamber (15), in which at least one of the first liquid chamber (14) and the second liquid chamber (15) has the elastic body (13) as a portion of a wall surface thereof, the partition member (16) includes an intermediate chamber (43) which is disposed inside the partition member (16), a first communication passage (42a) which communicates with the intermediate chamber (43) and the first liquid chamber (14), and a second communication passage (42b) which communicates with the intermediate chamber (43) and the second liquid chamber (15), and a barrier rigid body (33) which faces at least one of the first communication passage (42a) and the second communication passage (42b) is disposed inside the intermediate chamber (43).
