<p><P>PROBLEM TO BE SOLVED: To provide the integral connection structure of a hose and a metallic pipe easily securing the joint strength and sealing performance of a joint part at a low cost without making the outer diameter of the joint part excessively large. <P>SOLUTION: The hose 11 and the metallic pipe 12 are connected by a connecting fitting 13 to form the integral connection structure 1. The connecting fitting 13 is composed of a socket part 21 fitted to the end part of the hose 11, and an insertion part 22 inserted in the inner surface of the end part 25 of the metal pipe 12. Two ring-like grooves 23, 24 are formed on the outer peripheral surface of the insertion part 22. The end part of the hose 11 is inserted in the socket part 21 and fixed by caulking from the outer periphery. An O-ring is then fitted into the ring-like groove 23, and the insertion part 22 is inserted in the inner surface of the end part 25 of the metallic pipe 12. In this state, a part of the end part 25 is pressed from the outer periphery and caulked into the ring-like groove 24. <P>COPYRIGHT: (C)2004,JPO</p> |
