Abstract
A fluid filled vibration damping device includes an elastic body connecting a first and a second mounting member to close one opening of the second mounting member, and a lid member is fixed caulkwise to a shoulder of the second mounting member to close the other opening of the second mounting member, thereby providing a fluid chamber filled with a noncomporessible fluid. A partition member of outside diameter smaller than the inside diameter of the cylindrical caulking portion is formed with engaging projections rising up with a uplift cutout form. The engaging projections is fit into the second mounting member with the partition member superimposed on the shoulder so that the second mounting member is positioned in an axis-perpendicular direction to the second mounting member. Cutout openings left after the engaging projections have been formed are closed by a sealing portion.
