摘要： Each of blades of a centrifugal fan includes a primary wing section that has a trailing edge which is parallel to a central axis of rotation, a leading edge end section which is parallel to the central axis of rotation, and a thickness gradually growing thinner toward the trailing edge and the leading edge end section; and an auxiliary wing section that extends from the leading edge end section of the primary wing section toward the interior of the centrifugal fan. The auxiliary wing section has a length from the leading edge end section of the primary wing section to the leading edge of the auxiliary wing section that is greater at a side of a support section than at an intake side when viewed in a direction of the central axis of rotation, and a constant thickness across the entire area of the auxiliary wing section.
