Patent attributes
A fluid-filled cylindrical vibration-damping device including a main rubber elastic body elastically connecting an inner shaft member and an outer cylindrical member with each other. A pair of first fluid chambers are formed on diametrically opposite sides of the inner shaft member and a pair of second fluid chambers are formed being diametrically opposed to each other such that an opposing direction of the second fluid chambers is orthogonal to an opposing direction of the first fluid chambers. Each partition wall that partitions the first fluid chamber and the second fluid chamber extends in a direction in more proximity to the opposing direction of the first fluid chambers than to the opposing direction of the second fluid chambers so that spring rigidity as measured in the opposing direction of the first fluid chambers is set greater than spring rigidity as measured in the opposing direction of the second fluid chambers.
