PROBLEM TO BE SOLVED: To provide a connection structure of a pipe capable of increasing pipe holding force by caulking. SOLUTION: This connection structure of the pipe connects a built-in device 7 incorporated in a tank 6 filled up with a fluid to the pipe 8 disposed on the outside of the tank 6. The tip part of a joint 9 on the opening side of a hole part 9f is formed as a caulked part 9b on the flange part 8a of the pipe 8 and, in this state, the pipe 8 is brazed to the joint 9. The adjacent two sides of a line forming the hole part 9f form a triangular shape crossing a flange part 8a from one surface 8a1 to the other surface 8a2. COPYRIGHT: (C)2006,JPO&NCIPI
