Claims

[Claims for Utility Model Registration] (1) A cap nut to be hooked to the flange is slidably fitted onto a tubular member having a flange at its tip, and an annular nut is attached to the mating end surface of the connecting pipe part of the adapter. A ring groove is provided in the ring groove, into which a square ring is fitted, and the tubular member and the adapter are brought into contact with each other without a gap through the square ring, allowing communication between the inner holes. A pipe joint that connects a tubular member and an adapter by screwing the above-mentioned cap nut onto a screw, the ring groove having an inner circumferential wall surface and an outer circumferential wall surface inclined substantially parallel to the same direction, and having a square ring. A pipe joint characterized in that an inclined peripheral wall surface is restrained in a direction of insertion and removal in accordance with the direction of inclination of the peripheral wall surface of the ring groove. (2) The pipe joint according to claim 1, wherein the corner of the ring groove is formed into a curved surface.
