PROBLEM TO BE SOLVED: To provide an excellent pipe fitting jig with improved working accuracy and the workability while restricting a fluctuation of distance between a pipe and a working tool and a positional displacement of the angle of rotation by stabilizing the rotation of the pipe and capable of securing the high safety while preventing a fall off of the pipe by fixing the pipe. SOLUTION: A chuck part 4 is arranged freely to be rotated in a pipe fitting jig 15 at a position opposite to an end of a pipe 8. The chuck part 4 is rotated by the rotating force from a rotary driving device 10. Five pedestals 3 are fitted to the chuck part 4 with nearly equal space. An adapter 2 extended outward is connected to each pedestal 3. A claw part 1 is provided at a tip of the adapter 2. The claw part 1 is arranged on the circumference of the pipe 8, and formed with a pipe fixing part 5 to be brought in contact with the inner surface of the pipe 8.
