To attain increase in lift and reduction in resistance.SOLUTION: A high-lift device comprises a wing body part whose rear end part is formed in an acute angle shape, and an acute angle part solidified on the tip side of the wing body part. The height position of the tip point of the acute angle part on the cross section of the high-lift device exists between the projected lower end line of the high-lift device and the projected vertical center line of the high-lift device.SELECTED DRAWING: Figure 11

    【課題】 揚力の増加と抗力の減少を実現する。【解決手段】 高揚力装置は、後端部が鋭角状に形成された翼本体部と、前記翼本体部の先端側に固体された鋭角部と、備える高揚力装置であって、前記高揚力装置の断面における前記鋭角部の先端点の高さ位置は、前記高揚力装置の投影下端線から前記高揚力装置の投影上下中心線までの間に存在することを特徴とする。【選択図】図11
