The shaft coupling structure includes: a male joint, and a female shaft that is coupled to male joint. The outer peripheral surface of the male joint has an outer peripheral side concave-convex portion having a concave-convex shape in the circumferential direction and an annular concave groove, and the inner peripheral surface of the female shaft has an inner peripheral side concave-convex portion having a concave-convex shape in the circumferential direction. The outer peripheral side concave-convex portion and the inner peripheral side concave-convex portion engage with a concave-convex engagement. The outer peripheral surface of the male joint and an end portion on one side of the female shaft in the axial direction are welded and fixed together, and an embossed portion provided on the inner peripheral surface of the female shaft is arranged on the inner side of the annular concave groove.
