A fluid-filled vibration-damping device including: two elastically-connected attachment members; two liquid chambers divided by a partitioner having a storing space; an elastic mover disposed in the storing space and having a support supported by the partitioner; a positioner provided on at least one of radial inside and outside of the support, partially in a peripheral direction of the support, in abutment against a peripheral wall face of the storing space; a valve separate from the positioner in the peripheral direction, and the peripheral wall face in opposition; an axially-thin part connecting the positioner and the valve to the support in a displaceable manner; a communication passage connecting the liquid chambers formed between the peripheral wall face and the valve; and a switch configured to obstruct the communication passage by abutment of the valve against the peripheral wall face.
