PROPELLER FAN, ELECTRIC FAN AND CIRCULATOR

To provide a propeller fan capable of blowing air efficiently.SOLUTION: A propeller fan that rotates around a rotational axis and blows air in a first direction parallel to the rotational axis, comprises a hub part that rotates around the rotational axis, and a plurality of blades provided on the outer peripheral surface of the hub part. Each of the plurality of blades includes a first portion connected to the outer peripheral surface of the hub part, and a second portion farther from the rotational axis than the first portion. Each of the first portion and the second portion has a shape in which a rear part is curved toward the first direction with respect to a front part in the rotational direction, and a curvature angle of the rear part with respect to the front part is larger in the second portion than in the first portion.SELECTED DRAWING: Figure 2 【課題】効率よく送風することが可能なプロペラファンを提供する。【解決手段】回転軸を中心に回転し、前記回転軸に平行な第１方向に送風するプロペラファンは、前記回転軸を中心に回転するハブ部と、前記ハブ部の外周面に設けられた複数の羽根と、を備え、前記複数の羽根の各々は、前記ハブ部の前記外周面に接合された第１部分と、前記第１部分より前記回転軸から遠い第２部分とを含み、前記第１部分および第２部分の各々は、回転方向における前部に対して後部が前記第１方向に向かって湾曲した形状を有し、前記前部に対する前記後部の湾曲角度は、前記第１部分より前記第２部分の方が大きい。【選択図】図２
