Abstract
A vibration-damping device includes a partition member provided with an orifice passage that allows a main liquid chamber and an auxiliary liquid chamber to communicate with each other, a plurality of first communication holes that allows the main liquid chamber and an accommodation chamber to communicate with each other, and a second communication hole that allows the auxiliary liquid chamber and the accommodation chamber to communicate with each other. A tubular member that protrudes in an axial direction toward the elastic body is disposed on a first wall surface of the partition member to which the first communication holes are open and which constitutes a portion of an inner surface of the main liquid chamber. The plurality of first communication holes are open to both an inner portion located inside the tubular member and an outer portion located outside the tubular member, on the first wall surface.
