PROBLEM TO BE SOLVED: To provide an airtight jig for an opening part in which the opening part such as a pipe end can be airtightly closed in a safe manner with a simple configuration, a high airtightness can be held and the jig can be removed fast.SOLUTION: This invention relates to an airtight jig 1 for an opening part for airtightly closing an opening part 52 such as an end part of a pipe 50. The jig comprises: a cover member including a base plate 11 and a supporting piece 12; a hose band 20 for fixing the supporting piece 12 near the opening part 52; a pressing plate 30 applied with a pressing force through screwing of a bolt B; and a resilient member 40 disposed between the pressing plate 30 and the opening part 52. The supporting piece 12 is fixed with the hose band 20 in such a way that the base plate 11 is arranged at a position where it is spaced apart from and oppositely faces the opening part 52, the resilient member 40 is resiliently deformed by the pressing plate 30 and making closely contact with the circumferential edge of the opening part 52, thereby the opening part 52 is airtightly closed.SELECTED DRAWING: Figure 5 |
