FLUID-FILLED CYLINDRICAL VIBRATION-DAMPING DEVICE

摘要

A fluid-filled cylindrical vibration-damping device including: a main rubber elastic body elastically connecting an inner shaft member and an outer cylindrical member; a pair of first fluid chambers opposed to each other in a first diametric direction with the inner shaft member being interposed therebetween; and a pair of second fluid chambers opposed to each other in a second diametric direction orthogonal to the first diametric direction. Each partition wall that circumferentially partition the first fluid chambers and the second fluid chambers respectively extend between the inner shaft member and the outer cylindrical member in a direction in more proximity to the second diametric direction than to the first diametric direction. The main rubber elastic body is provided with a hollow portion so that at least a part of the wall of the second fluid chamber is defined by a thin-walled flexible film.
