摘要： In a manufacturing method of an impeller for a fluid transmitting device, multiple guide grooves aligned in a peripheral direction to allow communication between adjacent ones of multiple positioning holes are provided in a concave inner surface of a core in advance; and in a step of melting a brazing material and causing the molten brazing material to penetrate into gaps between coupling pieces and positioning holes that are fitted to each other and further into gaps between the core and the blades, the molten brazing material is guided to the positioning holes through the multiple guide grooves. Accordingly, the step allows the molten brazing material to be efficiently guided to the gaps between the coupling pieces and positioning holes, thereby improving the yield of the brazing material and preventing an influence of a residual brazing material over the rotational balance of the impeller.
