Abstract

PURPOSE: To enhance performance of a fan and realize high rigidity of an impeller by coaxially combining the predetermined number of impeller element of a cylindrical shape so as to form blade spaces each substantially enlarging from the inside toward the outside in the radial direction.
CONSTITUTION: A band plate 1 is cut and raised into an almost arcuate shape by means of a press machine to form blade portions 2 at predetermined arrangement pitches. In addition, preset blade portions 2' are formed in another band plate 1'. Coaxial combination of the given number of impeller elements 10, 10' in a cylindrical shape provides blade spaces each substantially enlarging from the inside toward the outside in the radial direction. Consequently, the arrangement pitch with respect to the length of the impeller can be reduced. Therefore, performance of a fan can be enhanced, and high rigidity of the impeller can be realized.
