Abstract (en)

A turbofan 10 includes a main plate 2 having a boss 2a that is a fixed portion to which a rotational shaft of a motor is secured, a plurality of blades 4, and a side plate 3 forming an inlet air guide wall. A blade trailing edge 4e has at least two inflection points on which the blade trailing edge 4e on the side of the main plate 2 convexly curves in the rotational direction and the blade trailing edge 4e on the side of the side of the side plate 3 concavely curves in the opposite rotational direction. Between a main plate side curved portion and a side plate side curved portion, the blade is formed such that the main plate 2 side is slanted in the rotational direction in relation to the side plate 3 side.
