PROBLEM TO BE SOLVED: To provide an insertion tool for a pipe inside investigation device that can positively maintain a guiding member for feeding an investigation device such as endoscope in a housed state when the guiding member is inserted in a pipe and positively and smoothly expand the guiding member when the guiding member is expanded in the pipe.SOLUTION: An insertion tool for a pipe inside investigation device comprises: a mounting member 25 to be detachably attached to a correction valve 5; an insertion member 27 disposed in the mounting member 25 so as to be vertically movable in a water-tight state; a holder 29 disposed at the lower end part of the insertion member 27 and able to accommodate an endoscope main body S; and a guiding member 31 held rotatably and vertically movably by the holder 29. The rotation of the guiding member 31 is restricted, with the guiding member 31 suspending from the holder 29, and the guiding member 31 is rotated and expanded as energized by torsion coil springs 107 when the guiding member 31 is pushed relatively upward with respect to the holder 29. As the insertion member 27 is pushed forward with the rotation of the guiding member 31 restricted and the tip of the guiding member 31 makes contact with a pipe bottom to move relatively upward with respect to the holder 29, the guiding member 31 is rotated and expanded.
