PROBLEM TO BE SOLVED: To provide a pipe joint capable of dispensing with a stop ring, and reducing the number of components.SOLUTION: A pipe joint 10 includes a main body member 12 having a flow channel 12D, and a nut 22 having an inner diameter larger than an outer diameter at one end 12G side in the axial direction, of the main body member 12, and externally inserted from one end side of the main body member 12 to be disposed on the other end 12H side in the axial direction, of the main body member. A projecting portion 12C having an outer diameter smaller than an inner diameter of the nut 22, is formed on an outer periphery at the other end side of the main body member 12. A thread groove 22A of the nut 22 is passed through the projecting portion 12C, and then a convex portion 22B formed on an inner periphery of the end portion of the nut 22 is brought into contact with the projecting portion 12C, so that movement in the direction separating from the other end side of the main body member 12, of the nut 22 is regulated. An exterior member 18 is mounted on an outer periphery at one end side of the main body member 12 after disposing the nut 22 on the other end side of the main body member 12, a pipe body 40 is inserted to an inner peripheral side of the exterior member 18, and a connection pipe 50 is connected to the nut 22. |
