Zusammenfassung:	PROBLEM TO BE SOLVED: To easily structure a pipe joint with a decoupling prevention function, for example, by reforming an installed pipe. SOLUTION: The pipe joint is provided to connect an end part 13 of a pipe 11 and an end part 14 of another pipe 12. A first annular groove 23 is formed at an inner circumference of the pipe 11 and a second annular groove 25 is formed at an inner circumference of the other pipe 12. A first annular body 32 for fitting in the first annular groove 23 is provided at the inner circumference of the pipe 11 and the second annular body 26 for fitting in the second annular groove 25 and being connected to the first annular body 32 while preventing decoupling in a pipe axis direction is provided at the inner circumference of the other pipe 12.
