Zusammenfassung:	A metal member coupling structure and a metal member coupling device that can perform high-strength and high-precision coupling are provided. A shaft-like portion 17 of the second metal member 12 is fitted in an annular portion 14 of the first metal member 11, a restraint ring 33 is disposed on the outer peripheral portion of the annular portion 14 of the first metal member 11, and the annular portion 14 is pressed to be plastically deformed, whereby the annular portion 14 is made to flow into a coupling groove 16 of the shaft-like portion 17 and the first metal member 11 and the second metal member 12 are coupled to each other through mechanical engagement therebetween.
