Claims

[Scope of utility model registration request]

In a structure in which a double flare shape is integrally provided at the end of a relatively thin-walled, small-diameter metal tube with a double bent circumferential wall that opens outward in a trumpet shape, the double flare 2 is formed by folding the inner circumferential wall 3 into a double flare shape. A connecting end structure for a small diameter metal tube, characterized in that the free end is extended and joined to the inner circumferential surface of the metal tube 2 with an inclined end tapered peripheral edge 5.
