Zusammenfassung:	To provide a ceiling fan widening the blowing range of an air flow.SOLUTION: A ceiling fan 1 includes mounting means 6 for fixing one end of a fixation axis 3 to a ceiling surface, a rotation part 4 rotating around the fixation axis 3 and a plurality of blades 7 fixed to the rotation part 4, and blows air by rotation of the blades 7 together with the rotation part 4. Auxiliary wings 20 having a prescribed height in an axis direction of the fixation axis 3 and rotating together with the blades 7 are connected to respective wing ends 7c of the blades 7. The auxiliary blades 20 are provided so as to extend longer than the blades 7 along the circumference of the rotation locus of the blade ends 7c with the fixation axis 3 as a center in a cross section perpendicular to the fixation axis 3.SELECTED DRAWING: Figure 2 【課題】気流の送風範囲を広げることが可能な天井扇を提供する。【解決手段】固定軸３の一端を天井面に固定することができる取付手段６と、固定軸３を中心に回転する回転部４と、回転部４に固定した複数の羽根７とを備え、回転部４とともに羽根７が回転して送風を行う天井扇１であって、羽根７のそれぞれの翼端７ｃには、固定軸３の軸方向に所定の高さを有し、羽根７とともに回転する補助翼２０が接続され、補助翼２０は、固定軸３に垂直な断面において、固定軸３を中心とした翼端７ｃの回転軌跡の円周に沿って、羽根７よりも延伸して設けられている。【選択図】図２
