A vibration-damping device (10) includes a first attachment member (11) having a cylindrical shape connected to any one of a vibration generating unit and a vibration receiving unit, a second attachment member (12) connected to the other unit, an elastic body (13) configured to connect both of the attachment members, and a partition member (15) configured to divide a liquid chamber (16) in the first attachment member (11) into a main liquid chamber (17) having a wall surface formed partly from the elastic body (13), and a subsidiary liquid chamber (18). In the partition member (15), an accommodating chamber (47) in communication with the main liquid chamber (17) and the subsidiary liquid chamber (18) through communication holes (46A, 46B) opened in an axial direction, an elastically deformable membrane (48) accommodated in the accommodating chamber (47) and separately exposed to the main liquid chamber (17) and the subsidiary liquid chamber (18) through the communication holes (46A, 46B), and restriction sections (51A, 51B) disposed more outside in the axial direction than the communication holes (46A, 46B) and overlapping the membrane (48) through the communication holes (46A, 46B) in the axial direction are installed. According to the vibration-damping device (10), performance of the membrane (48) can be maintained for a long period of time. |
