Abstract

In an impeller, where, in the case where imaginary cylinders concentric with a rotation axis are assumed, an imaginary cross-section of each of parts of each of blades that correspond to the imaginary cylinders is defined as a chordwise-direction cross-section; in the chordwise-direction cross-section, a straight line that connects the leading edge and the trailing edge is defined as a chord, and a central line of a cross-section of the blade is defined as a camber line; the distance between the chord and the camber line is defined as a camber height; on the camber line, a point equidistant from the leading edge and the trailing edge is defined as a camber midpoint; and a point at which the camber height is maximum is defined as a maximum extreme point, in the chordwise-direction cross-section close to the inner edge of the blade, the maximum extreme point is located closer to the trailing edge than to the camber midpoint and closer to an air suction side than to the chord, and the camber line has at least one inflection point between the leading edge and the maximum extreme point, and in the chordwise-direction cross-section close to the outer end of the blade, the maximum extreme point is located closer to the leading edge than to the camber midpoint and closer to the air suction side than to the chord.
