具。 A hollow shaft portion, circular or square flange portions integrally formed at both ends of the hollow shaft portion, and a plurality of flanges extending from these flange portions to the hollow shaft portion and making at least the flange portion deformable in the radial direction. This holder can be inserted into the reference shaft in the hollow of the pipe to be processed, and the reference shaft and the tightening collar fitted therein can be axially clamped. When the pipe is machined, the diameter of each of the flange parts simultaneously expands due to the tapered parts provided on each of the reference shaft and the tightening collar, so that the pipe comes into contact with the inner surface of the pipe to be processed. Holder for processing.
