Fluid-filled vibration damping device having a primary fluid chamber partial ly defined by an elastic body elastically connecting two spaced-apart mounting members and located on one of opposite sides of a partition structure having an orifice passage, an auxiliary fluid chamber partially defined by a flexible diaphragm and located on the other side of the partition structure, wherein the partition structure comprising an orifice including a pair of metallic annul ar components by pressing and are superposed on each other in an axial directio n thereof so as to define therebetween the orifice passage, the pair of annula r components being fixed together such that an inner peripheral portion of one annular components is bent to form a talking part which is talked to an inne r peripheral portion of the other annular member over an entire inner circumference of the orifice member, and the flexible rubber plate being bonded at an peripheral portion thereof to a surface of the talking part in a proce ss of vulcanization of a rubber material to form said flexible rubber plate.</SDOA B>
