Claims

[Claims for Utility Model Registration] 1. A metal round pipe 1 is concavely bent at multiple points in the circumferential direction over its entire length into a V-groove shape to form a ■-shaped pipe 2;
One end of the round pipe 1 with a shaped tube. is narrowed down to a constant diameter that can be inserted into the other end over a predetermined length by swage processing, and the middle part 2a of the V-shaped tube 2 at the narrowed small diameter end 1a is connected to the unsqueezed large diameter end. The small-diameter end 1a of one of the round pipes 1 is formed at the same time by the swage processing so as to leave a V-shape that deeply fits into the ■-shaped round pipe 2 of the part 1b, and The small diameter end 1 is fitted into the diameter end 1b.
Large diameter end 1b of another round pipe 1 in V-shaped tube 2 of a
A metal tube for torque transmission, characterized in that the V-shaped tubes 2 can be connected by stopping the supports from both sides in the circumferential direction. 2. In the metal tube for torque transmission described in claim 1 of the utility model registration, a bulge 1C is formed at the tip of the small diameter end 1a of the round pipe 1 to prevent rattling.
