A shaft coupling structure of a plurality of shafts of a torque transmitting shaft in which, even in a case where defects occur in a weld portion, it is possible to maintain a torque transmitting function and it is possible to prevent separation of the plurality of shafts. Of a male joint 46 and a female shaft 30 that are coupled together, the outer peripheral surface of the male joint 46 is provided with an outer peripheral side concave-convex portion 58 having a concave-convex shape in the circumferential direction and an annular concave groove 57, and the inner peripheral surface of the female shaft 30 is provided with an inner peripheral side concave-convex portion 41 having a concave-convex shape in the circumferential direction; and the outer peripheral side concave-convex portion 58 and the inner peripheral side concave-convex portion 41 engage with a concave-convex engagement. The outer peripheral surface of the male joint 46 and an end portion on one side of the female shaft 30 in the axial direction are welded and fixed together, and an embossed portion 62 provided on the inner peripheral surface of the female shaft 30 is arranged on the inner side of the annular concave groove 57.
