PROBLEM TO BE SOLVED: To provide a pressure means, which is capable of pressing a work with high pressure by depressurizing only a pressure jig, where the work is put in the pressure jig, and the pressure jig is depressurized to press the work. SOLUTION: A work 1 is introduced into a pressure jig 2, which can be partially or fully deformed and is provided with an opening through which the pressure jig can be exhausted or air can be fed into the pressure jig, and the pressure jig 2 is depressurized to press the work. Furthermore, the pressure jig 2 is pressurized by a means, which presses fluid outside the pressure jig 2 and/or another means which fills the outside of the pressure jig with fluid. For instance, fluid between the pressure jig 2 and a pressure jig 3 is pressed, or a gap between the pressure jig 2 and pressure jig 3 is filled with fluid. |
