<p><P>PROBLEM TO BE SOLVED: To provide a pipe body connection structure capable of connecting both pipe bodies to each other in a properly sealed condition with simple work, without using a fixing member such as a clamp or a collar. <P>SOLUTION: An annular bead part 3 swollen to the outside is formed at the front end of an inner pipe 1, and a flare part 4, with its diameter enlarged, is formed at the front end of an outer pipe 2. The bead part 3 is inserted into the inside of the flare part 4 and arranged in a condition of abutting against an abutting portion 5 of the flare part 4; and then by caulking the flare part 4 with its diameter contracted along the outer periphery of the bead part 3, the bead part 3 can be sealed with the abutting portion 5 of the flare part 4. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
