PURPOSE:To carry out pipe cutting smoothly by arranging a push-pressing force receiving member in the tip part of a cylindrical body so that push-pressing force can be received from outside of a pipe when a cutter is cut into the pipe. CONSTITUTION:A shaft shape body 7 is inserted into a cylindrical body 6, which is provided with a cutter 5 to cut into a pipe from inside, on the tip side so as to be operated freely, and a pipe inside surface receiving member 10 situating on the opposite side of the diameter direction is also arranged in the cylindrical body 6. The clearance between the cutter 5 and the pipe inside surface receiving member 10 is constituted so as to be expanded/contracted freely according to operation of the shaft shape body 7, and a push-pressing force receiving member 11, which receives push-pressing force from inside of the pipe when the cutter 5 is cut into the pipe by expanding the clearance, is arranged in the tip part of the cylindrical body 6. Thereby, since the push-pressing force applied by the cutter 5 can be received in the cutting place of the pipe by means of the push-pressing force receiving member 11, by operation in which a cut/removed part of the pipe is moved outward to expand its diameter, the tip part of the pipe can be prevented from being bent, so that the pipe cutting can be carried out smoothly.
