PROBLEM TO BE SOLVED: To provide a structure of a pipe joint not requiring the flaring or the like of a refrigerant piping connection end part without providing another component, facilitating connection work, and realizing a certain connection state. SOLUTION: In this structure of the pipe joint, the straight connection end part 2b of a pipe 2 to be connected is inserted and fitted in a connection port part 31g of a tube-like connection port body 31, a flare nut 5 is screwed onto the periphery to the connection port body 31 side from the connection pipe 2 side through a detachment-preventing bite type sleeve 32, and the bite type sleeve 32 is bitten into the connection pipe 2 by the fastening force of the flare nut 5 to connect and fix the pipe 2 and the connection port body 31. The bite type sleeve 32 is integrally formed on the tip side as a part of a peripheral wall of a fitting part of the connection port part 31g on the connection port body 31 side. Thereby, the other component is not required, and the connection work is facilitated. |
