Abstract: PURPOSE:To ease assembling work of blades to a core and to automate the work for an impeller, in which a plurality of blades are assembled through claw-engaging of a semi-annular shell, by conducting the assembly work of the blades on the core side through claw-engaging, in which two semi-annular cores rotating in the opposite direction to each other are used. CONSTITUTION:In assembling an impeller, a plurality of blades 12 are installed on a shell 10 by fitting a claw part on the shell side of the blades 12 into a blade-installing groove of the shell 10. Next, a first core 14 and a second core 16 are arranged overlapped with each other on the core side (opposite to the shell side), with a slit 14b and a slit 16b, which are formed into a comparatively large shape, coinciding with each other. At the same time, a claw part 12b, which are projected from the blade 12, are fitted to the slits 14b, 16b. In this state, the cores 14,16 are rotated in the opposite direction to each other, so that the claw part 12 gets in between opening-edge parts of the slits 13b, 16b situated on the opposite side to each other, thereby conducting the positioning of the claw part 12b. Next, the claw part 12b is folded, and this part is joined by brazing to complete the impeller.
