A vibration-damping device includes: an elastic body connecting a tubular first mounting member and a second mounting member; and a partition member (8) partitioning a fluid chamber within the first mounting member, the fluid chamber being filled with fluid, into a primary fluid chamber on one side and an auxiliary fluid camber on another side. The partitioning member (8) includes: the limiting passages (70, 71) communicating between the primary and the auxiliary chambers, and generating fluid column resonance with respect to input vibration, thereby damping and reducing the vibration; switching device (1072, 2072) switching between the resonance frequencies of the limiting passages (70, 71); a connection passage (74) connecting the primary and the auxiliary chambers; a fluid pressure introducing passage (74) into the switching device (1072, 2072) to operate the switching device (1072, 2072); and a thin film body (73) provided within the connection passage (74), and blocking the communication between the primary and the auxiliary fluid chambers via the connection passage (74). |
