<p>PROBLEM TO BE SOLVED: To provide a pipe cutting device which allows anybody to easily cut a pipe from its inside.SOLUTION: A cylindrical rotary part 110 allows the movement of a rotary shaft part 10 in its center axis direction and is configured to be rotatable in accordance with rotation of the rotary shaft part 10. The rotary shaft part 10 and a pair of projections 12, 12 are arranged inside the cylindrical rotary part 110 so that the pair of projections 12, 12 are engaged with a pair of cutting blade holding parts 120, 120. The movement direction of the pair of cutting blade holding parts 120, 120 is restricted to a direction approximately orthogonal to the center axis direction of the rotary shaft part 10. A first non-rotary part 140 is mounted to a rear end of the cylindrical rotary part 110 so as not to rotate in accordance with rotation of the cylindrical rotary part 110. A cutting position adjusting member 150 having a flange part 152 abutting on an edge of a pipe is provided on a side surface of the first non-rotary part 140.</p> |
