がある。(Problems to be solved by conventional techniques and inventions) As shown in Fig. 5, conventional gas pipes and pipe fittings have a tapered pipe thread b carved into the opening A1 at one end of the pipe body. However, this is because the taper screw b is cut by cutting the taper screw b with a die, so one end opening a 1 of the pipe body a
Not only does the wall thickness of the thread become thinner, but the structure of the material is cut, which may reduce the effective strength of the thread.

る。 On the other hand, the tapered thread of the pipe body a shown in FIGS. 6 and 7 is a pipe taper thread b manufactured by using a thread rolling machine die. Since the tapered thread is formed by pressing a rolling die without cutting the threads, the structure of the material is not damaged and the effective strength of the thread is not impaired. Thread rolling machines have a holding mechanism that holds the rolling dies and are configured to link a link mechanism and a cam mechanism, which not only increases the number of component parts but also makes the structure complex, requiring assembly adjustments and maintenance. Inspection is troublesome, and
The entire device is large and difficult to handle, and furthermore, because it is heavy, it is difficult to carry it to a work site where pipes are installed.
