Abstract

PURPOSE: To improve productivity of the multivane fan by a method wherein a vane piece cut off rectilinearly at both ends is inserted in a groove formed in a disc of the multivane, a triangular part on the outer side of the groove is press-attached to the outside of the vane piece.
CONSTITUTION: The vane piece 4 is made a slender piece formed in a circular arc-shape and both ends thereof are cut off rectilinearly. The piece 4 is inserted into the groove 5a of the disc 5 with the disc 5 remaining arranged at a prescribed interval. After that, the triangular part 5d outside an external border line of the groove 5a of the disc 5 is collapsed and press-attached on the external surface of the vane piece 4, and also the vane piece 4 on the end side is formed a projection to permit the vane piece 4 and the disc 5 to securely be fixed with each other. Thus, since the vane piece 4 of which both ends are cut off rectilinearly is used, the productivity can be improved with a good yield.
