| description | PURPOSE:To realize such a shape of a hub as to make a flow of wind preferable, obtain excellent performance, improve carrying performance, and a compact air conditioner contributable to energy conservation by improving shapes of the head of the hub, a rib, a boss and a blade facilitating manufacturing work, enhancing stacking performance and strength, and using a propeller fan as an assembly. CONSTITUTION:A hub 2 is constituted of a largely round head 5 and a cylindrical portion 7 having a larger inner diameter, i.e., a smaller thickness, toward an opening 7a. A dimension of a step portion 6 between the head 5 and the cylindrical portion 7 is reduced. Accordingly, the end of the cylindrical portion 7 is overlapped on the head 5 of other fan when fans are laminated. The opening end of a reinforcing rib 4 is formed in such a manner as to mate with a shape of the head 5 at the time of stacking so that an axial width of the rib is enlarged and a line perpendicular to an axis is formed at the final edge of a blade 1. Furthermore, a projection 3a of a boss 3 can be inserted into a center recess 8 of the head 5 of the hub 2 of other fan. Consequently, it is possible to enhance stacking performance. |
