Abstract:
An impeller of a centrifugal fan includes multiple blades arranged annularly around a rotational axis, a main plate, a shroud, main plate-side welded portions between main plate-side blade axial ends of the blades and the main plate, and shroud-side welded portions between shroud-side blade axial ends of the blades and the shroud. The main plate is arranged opposite to main plate-side blade axial ends. The shroud is arranged opposite to shroud-side blade axial ends. The main plate-side welded portions have main plate-side welding holes that are recesses extending through the main plate to portions of the main plate-side blade axial ends. The shroud-side welded portions have shroud-side welding holes that are recesses extending through the shroud to portions of the shroud-side blade axial ends.

Claim (Index 8):
A method for manufacturing an impeller of a centrifugal fan, the impeller being manufactured by welding between multiple blades arranged annularly around a rotational axis and a main plate and a shroud, the main plate and the shroud being respectively arranged opposite to two blade axial ends that are both ends of each of the blades along a direction of the rotational axis, the method comprising:\n welding between the main plate and a main plate-side blade axial end that is one of the two blade axial ends of each of the blades and welding between the shroud and a shroud-side blade axial end that is an other of the two blade axial ends of each of the blades, ultrasonically vibrating the blades and the main plate and melting the main plate-side blade axial ends and the main plate so that main plate-side welding holes ( 8 d ) that are recesses extending through the main plate to portions of the main plate-side blade axial ends are formed; and ultrasonically vibrating the blades and the shroud and melting the shroud-side blade axial ends and the shroud so that shroud-side welding holes that are recesses extending through the shroud to portions of the shroud-side blade axial ends are formed.
