PROBLEM TO BE SOLVED: To provide a device for introducing an installation unit capable of accurately introducing the installation unit only by feeding a shaft member without forming a special portion for introducing the installation unit to a casing.SOLUTION: There is provided a device for introducing an installation unit for allowing a shaft member 8 having a blade member connected thereto to circumferentially rotate and to axially advance/retract in a casing 2 hermetically attached to a fluid pipe 1 to cut the fluid pipe 1 or forming an opening therein and disposing the installation unit 37 to the cut or opened porting using a shaft member 6 in a predetermined direction in a state where fluid flow does not stop. The installation unit introduction device at least includes a connection part 81 which is provided to the shaft member 8 to fix the direction of the installation unit 37, a rotation member 12 for rotating the shaft member 8, an advancing/retracting member 13 for advancing/retracting the shaft member 8 in the axial direction via the rotation member 12, and a rotation restriction member 15 for restricting the rotation of the rotation member 12 relative to the advancing/retracting member 13. |
