Abstract

PURPOSE: To enable an assembly under automatic supplying of a blade and reduce man-hours therefor by a method wherein a work to supply the blade to the main plate and the side plate of an impeller is facilitated in a blade inserting work.
CONSTITUTION: The tip parts 11 for inserting a blade 6 into slits 9, 10 of the main plate 7 and the side plate 8 are provided at both sides of the blade 6 and the slit 10 of the side plate 8 is reached to an inner periphery of the side plate, therefore, the blade 6 may be inserted from the inner peripheral side thereof. A stepped part 12, having a L-shaped section and extending to an axial direction thereof, is provided at an outer periphery of the main plate 7 and the slit 9 of the main plate 7 is extended to the stepped part. The main plate 7 and the side plate 8 are facedly arranged with a predetermined interval, while the blade 6 is inserted from inside of a radial direction through an extension of the slit and is reached to a predetermined position at outer peripheral parts of the side plate 8 and the main plate 7, thereafter, the terminal parts of the blade 6 are bent and fixed at outer sides of the main plate 7 and the side plate 8.
