5 is applied to the large-diameter step portion 12. Further, the pipe positioning member 6 is fitted and fixed in the cut groove 53 of the connecting member 5. That is, the hook 65 is removed from the pin 66 and the flat plates 61 and 62 are removed.
Is opened with the pin 64 as a fulcrum, the cut portions 67 and 68 are fitted into the cut grooves 53, the flat plates 61 and 62 are closed,
On the pin 66. At this time, the pipe positioning member 6
Is directed in a direction orthogonal to the bending angle of the coupling member 5. Next, one of the pipes P is inserted into the guide member 2 so as to be fitted to the outside, the welded end face of the pipe P is applied to the pipe positioning member 6, and the pre-marked position (not shown) of the pipe P is set to Flat plates 61, 6
After turning the pipe P so as to coincide with the mating line 69 of FIG. 2, the conical member 4 is pushed in by screwing the tightening nut 20 into the male screw 13, and then the expanding member 3 is moved in the radial direction. By moving and pressing the inner surface of the pipe P,
The shaft 1 and the coupling member 5 are fixed to the pipe P, and the center line of the pipe P coincides with the axis of the shaft 1.

芯、パイプ間の隙間を容易に決定することができる。Next, the cap nut 16 of the other shaft 1 is screwed into the fifth male screw 52 of the connecting member, and the support plate 25, the seal rubber plate 24, and the guide member 2 are sequentially mounted on the shaft 11 in the same manner as described above. The support plate 25 is fitted to the large-diameter step portion 12. Next, the other pipe P is inserted into the guide member 2 so as to be fitted to the outside, the welded end face of the pipe P is applied to the pipe positioning member 6, and the pre-marked position (not shown) of the pipe is set to the flat plate of the pipe positioning member 6. 61,6
After turning the pipe so as to coincide with the joining line 69 of 2, the conical member 4 is pushed in by screwing the tightening nut 20 into the male screw 13, and the expanding member 3 moves in the radial direction. By pressing the inner surface of the pipe P, the shaft 1 and the coupling member 5 are fixed to the pipe P, and the center line of the pipe P coincides with the axis of the shaft 1. Therefore, the bending angle of both pipes P and the bending angle of the connecting member 5 match. When the bending angle of the two pipes P and the bending angle of the connecting member 5 match, when the pipe positioning member 6 is removed, a predetermined abutting gap is formed between the two pipes P. Welding produces a bend tube. In this manner, both pipes can be fixed at the angle set by the connecting member 5. Further, the pipe positioning member 6 can easily determine a fixed position in consideration of welding, that is, a circumference, a core in the pipe axial direction, and a gap between the pipes.

At this time, the gas blown into the space in the pipe is sealed by the sealing rubber plate, and leakage to the outside is reliably prevented. In the case where there is a change in the bending angle of the pipe or a large change in the pipe diameter, the expansion member 3, the conical member 4, the connecting member 5, and the like can be easily replaced.
