Zusammenfassung:Provided is a fluid-filled cylindrical vibration-damping device having a novel structure, the vibration-damping device being capable of exhibiting excellent vibration-damping performance against vibration in both low- and high-frequency regions, which is inputted in a direction perpendicular to an axis. This fluid-filled cylindrical vibration-damping device 10 is configured such that: an intermediate cylinder member 14 is disposed over the outer periphery of an inner shaft member 12 at a distance therefrom; the intermediate cylinder member 14 and the inner shaft member 12 are connected by a main body rubber elastic body 16; an outer cylinder member 18 is fitted over and affixed to the intermediate cylinder member 14; fluid chambers 58 are formed between the inner shaft member 12 and the outer cylinder member 18 at positions on the opposite sides of the inner shaft member 12; and an orifice passage 60 is provided to provide communication between the fluid chambers 58 on the opposite sides. At least one axial s
