Beschreibung
Zusammenfassung:	A method of connecting metal materials to each other, wherein a pin fitted to the tip of a metal bar-like rotating tool ( 10 ) is inserted between the end pan of a metal member (I) and the end part of a metal member ( 1 '), and moved, while rotating, along the longitudinal direction of these end parts. By this frictional heat is generated between the metal members ( 1 ) and ( 1 ') and the rotating tool ( 10 ), and the metal member ( 1 ) is connected to the metal member ( 1 '). The rotating tool ( 10 ) is formed of a wide shoulder ( 12 ) and a thin pin ( 11 ) formed at the tip thereof and inserted between the end parts of the metal members. The pin ( 11 ) is a right circular cylindrical pin. The side face of the pin ( 11 ) is formed in a smooth curved surface, and a thread groove is not formed therein.
