Abstract

PURPOSE: To reduce man-hours for assembling by a method wherein a stepped part is provided on a main plate and a side plate of an impeller, slits are provided at inner sides thereof while nicks parallel to the longitudinal direction of a blade and projections are provided at both terminal parts of the blade.
CONSTITUTION: Nicks 12 parallel to a longitudinal direction of a blade and projections 11 are provided at both end parts of the blade 6, stepped parts 13 having L-shaped sections are provided on a main plate 7 and a side plate 8 of an impeller and slits 9 are provided at inner sides than these stepped parts. An inner side part of the end of the blade 6 is fitted into the slit 9, thereafter, are bent at an outside of the main plate 7 or the side plate 8 while the outside part (projection) of the end of the blade is bent inwardly with respect to the main plate 7 or the side plate 8 to fix the blade 6. Accordingly to this method, the blade 6 may be inserted while a predetermined interval between the main plate 7 and the side plate 8 is being kept and a sturdy aseembling is enabled, therefore, man-hours for the assembling may be reduced remarkably.
