DEPRESSURIZING JIG AND METHOD FOR PRESSURIZING OBJECT BY USING DEPRESSURIZING JIG

摘要

A depressurizing jig capable of depressurizing a pressurized object after the space in which the pressurized object is received is sufficiently depressurized, and a method for pressurizing the pressurized object using the depressurizing jig. The pressure reducing jig 1 is constituted by combining the first pressure reducing member 10, the second pressure reducing member 20, the sealing member 30, the first preliminary pressure reducing member 40 and the second preliminary pressure reducing member 50 . The first pressure-sensitive member 10 is formed by spreading a first sheet member 12 made of a sheet-like member having flexibility in the first frame member 11. [ The first frame member 11 is formed with an exhaust passage 15 connected to the exhaust means through the exhaust port 14 and communicating with the accommodation space S. [ The first preliminary pressure reducing member 40 is configured to form a preliminary pressure reducing chamber Y between the first pressure reducing member 40 and the first sheet member 12 so as to reduce the pressure inside the preliminary pressure reducing chamber Y.
