A fluid-filled vibration damping device including a main rubber elastic body composed of a first rubber elastic body and a second rubber elastic body which are overlapped in an axial direction, and a pair of axis-perpendicular liquid chambers formed between the first and second rubber elastic bodies. A pair of dividing walls which divide the axis-perpendicular liquid chambers are constituted by a first division piece protruding from the first rubber elastic body and a second division piece protruding from the second rubber elastic body being overlapped in a circumferential direction. The first rubber elastic body has a thickness, diameter and spring constant all set larger than those of the second rubber elastic body, while having a tapered shape. With the device mounted on a vibration transmission system, a static support load is input so as to compress the first rubber elastic body.
