<p><P>PROBLEM TO BE SOLVED: To provide a pipe mounting structure capable of preventing coming off of the pipe solidly relative to a conventional one, and a pipe joint. <P>SOLUTION: In this pipe mounting structure, a thin-wall pipe 20 to be fitted to the outside of a tip part of a pipe 90 is formed in order to fix the tip part of the pipe 90 in a state fitted to the outside of a nozzle 13; an annular valley part 25 forming a groove-like shape on the outer surface side of the thin-wall pipe 20 and forming a projection-like shape on the inner surface side of the thin-wall pipe 20 is formed in the entire circumference at an axial intermediate position of the thin-wall pipe 20; the groove-like shape of the valley part 25 is formed into a shape where areas from respective opening edges on both sides of the groove opening to the groove bottom face 25B are each formed into a curved shape in an S-shaped form while the groove width gradually increases as approaching the groove opening from the groove bottom face 25B; the inner diameter of the valley part 25 is reduced by compressively pressurizing the valley part 25 in the axial direction of the thin-wall pipe 20 to be plastically deformed; and thereby the pipe 90 can be fastened to the nozzle 13. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
