A partitioning member partitioning two liquid chambers includes an orifice forming member, an elastic wall configured to close an inner peripheral surface thereof, and a pair of partitioning plates which hold the elastic wall from both sides in an axial direction X The pair of partitioning plates includes a holding portion configured to hold the elastic wall radially outward Ko of a coupling portion. The holding portion comprises a first holding portion on the radially outside and a second holding portion on the radially inside, and the first holding portion is provided with a high-compression holding portion having a compression ratio higher than that of the second holding portion. Accordingly, the abnormal sound is reduced while achieving both the damping performance in the low frequency range and the lowering of the dynamic spring constant in the high-frequency range without impairing the assembleability of the partitioning member. |
