Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an opening part closing device for cylindrical structure pressure test repeatedly usable by use of the pressure in the test for the fixation of a device used for closing an opening part in pressure test. SOLUTION: A cylindrical structure opening part closing jig 28 as this device is formed of a disc-like closing plate 3 for preventing the outflow of an internal fluid and a body 21 having a structure for transmitting the pressure of the internal fluid in a pressure test to a support leg part 22. Since welding is not used for the fixation of the jig 28, the influence on a base material in the attachment and detachment can be avoided. Further, since this jig is repeatedly usable, the material cost can be reduced.
