| description | PROBLEM TO BE SOLVED: To assemble an impeller for a pump simply by press work only so as to be manufactured at a low cost. SOLUTION: A plurality of projections 18a are arranged on the upper surface of a blade 18 formed on the main surface of the base plate 16 of an impeller 12 at predetermined bending rate and height. While, in a shroud 14 with which the upper surface of the blade 18 of the impeller 12 is covered, a plurality of holes 14a are formed in positions matched to the projections 18a arranged on the blade 18 of the impeller 12. The projections 18a on the blade 18 are inserted in the holes 14a of the shroud 14, and the upper surface of the impeller 18 is brought in contact with the lower surface of the shroud 14. Hereupon, the impeller 12 and the shroud 14 are integrated without applying ultrasonic welding. |
