PURPOSE: To provide a method of manufacturing a fluid-filled mount advantageously reduced or prevented from the rise of pressure in a fluid chamber at the time of manufacture. ;CONSTITUTION: The fit-in part 50 of a partition member 38 is inserted into a second bracket 14, and the outer peripheral edge part 46 of the partition member 38 is supported by the supporting part 33 of the second bracket 14. In this state, the second bracket 14 is subjected to drawing while impeding the deformation of a flexible film 30 in a specified incompressible fluid 62. At the time of forming an orifice passage by covering a peripheral groove 44, provided at the fit-in part 50, with the second bracket 14, internal pressure generated in the second bracket 14 is let escape to the outside through a pressure relief passage 58 formed at the outer peripheral edge part 46 of the partition member 38.;COPYRIGHT: (C)1995,JPO
