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