Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a blade for a cross flow fan that makes a blowing condition and timing uneven along an axial direction to reduce the load acting on the blade at one time, thereby preventing vibration and noise, and to provide a cross flow fan.SOLUTION: The blade for a cross flow fan is extended along an axial direction of a cross flow fan and formed so that a position of the radially outer peripheral end thereof varies along the axial direction. Thus, a blowing condition and timing is made to be uneven in the axial direction and the load acting on the blade for a cross flow fan at one time is reduced to thereby prevent vibration and noise.SELECTED DRAWING: Figure 5 【課題】送風時の条件及びタイミングを軸方向に沿って不均一化することで羽根に同時に作用する負荷を軽減して振動や騒音を防止できるクロスフローファン用羽根とクロスフローファンを提供すること。【解決手段】クロスフローファンの軸方向に沿って延長されその放射方向外周端位置が軸方向に沿って変化するように形成されたことを特徴とするクロスフローファン用羽根により、送風時の条件及びタイミングを軸方向に不均一化して、上記クロスフローファン用羽根に同時に作用する負荷を軽減して振動や騒音を防止するもの。【選択図】図５
