CENTRIFUGAL FAN

摘要

A centrifugal fan (23) includes a hub (15), a plurality of blades (21), and a shroud (19). The blades (21) each have a curved part (21d) that is curved to incline toward a side (21c1) on which air impinges when a connected end (21c) connected to an inwardly protruding portion of the shroud (19) moves in a rotating direction of the centrifugal fan (23). The hub (15) includes a hub-side diffuser ring (27) that protrudes radially outward of the blades (21). The shroud (19) includes a shroud-side diffuser ring (26) that protrudes radially outward of the blades (21).
