Zusammenfassung:	An impeller for a fluid transmitting device includes a hub 2h, 3h and a bowl-shaped shell 2s,3s connected to an outer peripheral portion of the hub 2h,3h via an annular weld seam 40. An inner peripheral surface of the she112s, 3s is fittedto an outer peripheral surface of the hub 2h, 3h, and the weld seam 40 is formed therebetween by laser welding over an entire length of fitting depth. Thus, it is possible to form the annular weld seam 40 between the hub 2h, 3h and the shell 2s,3s with a relatively small amount of heat input, and to precisely perform a visual inspection as to whether the weld seam 40 is good or not without any skill.
