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 13):
The method for manufacturing the impeller of the centrifugal fan according to  claim 8 , wherein\n the shroud has a blade-side shroud surface arranged opposite to the shroud-side blade axial ends and an opposite-blade-side shroud surface that is an opposite surface of the blade-side shroud surface along the direction of the rotational axis, the method further comprising:\n forming shroud flat surfaces on the opposite-blade-side shroud surface; and \n ultrasonically vibrating the blades and the main plate from portions of the main plate that are arranged opposite to the shroud flat surfaces along the direction of the rotational axis, while pressing the shroud flat surfaces toward the main plate, when welding between the main plate-side blade axial ends and the main plate.
