Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a gas conduit shutdown tool free to work at a narrow part incapable of securing a setting space of a squeezing device and to carry out a perfect no-blow work by the simple work. SOLUTION: The tool is fixed in the conduit by holding a holding body 11 of a holder 1 on an outer periphery of the conduit. A drilling injector 2 is mounted on a mounting part 11a provided on the holding body 11, the conduit is drilled by screwing a screw part 23b of a drilling blade 23 in a mounting hole 13, and a head end opening 23a is made to intrude in the inside of the conduit. Grease is injected into the inside of the conduit through an inflow passage 24 by connecting a connecting hose of a grease injection pump to a connecting part 20. A valve part 21 to open and close the passage is provided in the inflow passage 24.
