Abstract
A fluid-filled vibration-damping device including two chambers partitioned by a partition member and mutually communicated by an orifice passage and a communication passage which is provided at the partition member, with a movable rubber film disposed in the communication passage so that each pressure of the chambers is applied to the respective face of the movable rubber film, wherein the movable rubber film includes a thick-walled outer peripheral retaining part formed at its outer rim and clamped by the partition member and reinforcing crosspieces projecting on its face and extending inward from the outer peripheral retaining part to mutually intersect, and a width dimension of at least one of the reinforcing crosspieces is made small in a vicinity of the intersection part to provide a narrow part by which the movable rubber film has a low-spring area in the vicinity of the intersection part.
