<p>This vibration-damping device (10) comprises: a partitioning member (17) that forms a main liquid chamber (14), and an auxiliary liquid chamber (15) and an intermediate chamber (16) that are provided independently from the main liquid chamber (14), a portion of the wall surface of the main liquid chamber being formed by an elastic body (13); and an elastic membrane (19) constituting a portion of the wall surface of the intermediate chamber (16). The partitioning member (17) is provided with: a first restriction channel (31) that connects the main liquid chamber (14) and the auxiliary liquid chamber (15); a second restriction channel (33) that extends from the main liquid chamber (14) toward the intermediate chamber (16) and that has a smaller circulation resistance than the circulation resistance of the first restriction channel (31); and a movable body (35) that is arranged between the second restriction channel (33) and the intermediate chamber (16). An adjustment chamber (24) having an interior that can be decompressed or compressed with respect to standard pressure, or having an interior that is open such that the same can be blocked off from the outside, is provided adjacent to the intermediate chamber (16) across the elastic membrane (19). With this configuration, it is possible to offer damping characteristics against vibrations over a wide range of frequencies.</p> |
