Abstract

PURPOSE: To improve productivity of the multivane fan by a method wherein a vane piece cut off rectilinearly at both ends is inserted into a groove formed in a disk of the multivane fan, and a triangular part bent on the outer side of the groove is returned to the original state and collapsed to be press-attached to the vane piece on the outer side.
CONSTITUTION: The vane piece 4 is made a slender piece formed in a circular arc-shaped, and cut off rectilinearly at the both ends. The triangular part 5d on the outer side of an external border line 5b of the disk 5 is bent to make a gap of the groove 5a wide. Then, the vane piece 4 is inserted in the groove 5a of the disk 5 with the disk remaining arranged at a prescribed interval. At this time, the vane piece 4 is engaged by a projection 5b. Thereafter, when the triangular part 5d on the outer side of the external border line of the groove 5a formed in the disk 5 is collapsed while being returned to the original state, the collapsed part is press- attached to the vane piece 4 on the outer surface to allow the vane piece 4 and the disk 5 to be fixed with each other. Thus, using the vane piece 4 cut off rectilinearly at both ends makes a yield well and effects improvement of the productivity of the multivane fan.
