Abstract
A fluid-filled vibration-damping device including: a first mounting member; a second mounting member; a main rubber elastic body elastically connecting the two mounting members; a fluid chamber whose wall is constituted by the main rubber elastic body at a portion and by a flexible film at another portion, the fluid chamber being filled with a non-compressible fluid; a fixation member being attached to an outer peripheral rim of the flexible film and being disposed inside or outside the tubular second mounting member such that the fixation member is superposed to the second mounting member in an axis-perpendicular direction; an insertion hole formed in the second mounting member and the fixation member; and a positioning member inserted through the insertion hole so as to relatively position the second mounting member and the fixation member at a scaling position by axial locking.
