Abstract
Official abstract text for this publication.
An impeller is fixed to a shaft concentric with a center axis extending in an up-down direction and is rotatable about the center axis together with the shaft. The impeller includes a boss portion which is fixed to the shaft and extends in an axial direction, an impeller body portion, a plurality of blade portions arranged on an upper surface of the impeller body portion, and a rib portion arranged on a lower surface of the impeller body portion. The impeller body portion extends downward from an upper end of the boss portion while being widened in a radial direction, and is arranged to surround the boss portion in a circumferential direction. When viewed in the axial direction, a front side end portion of the rib portion is curved toward a rotation direction back side as the rib portion extends from a radial inner side toward a radial outer side.
