To suppress blade parts of a windmill from rotating excessively to reduce influence of friction and suppress enlargement of an overrotation suppression mechanism, without the axial movement of an arm.SOLUTION: A lift-type vertical axis wind turbine 1 includes a rotation hub 3 and wind turbine blade parts 4. The wind turbine blade part 4 has an arm 41 and a blade 42. The arm 41 is provided so as to twist around a rotational axis Y of the arm 41. The lift-type vertical axis wind turbine 1 further includes a tuning mechanism 6 that tunes the rotations of the arms 41 about the rotation axis Y with each other, and an energization member SP that energizes the arm 41 in a direction in which a wind receiving area of the blade 42 increases.SELECTED DRAWING: Figure 2 【課題】本発明は、アームの軸方向の移動を伴わずに、風車の翼部の過回転を抑制し、摩擦の影響を減らすとともに過回転抑制機構の大型化を抑制することを目的とする。【解決手段】揚力型垂直軸風車１は、回転用ハブ３と風車翼部４を備え、風車翼部４は、アーム４１とブレード４２とを有し、アーム４１は、アーム４１の回転軸Ｙ周りにツイストするように設けられ、揚力型垂直軸風車１がさらに、アーム４１の回転軸Ｙ周りの回転を互いに同調させる同調機構６と、アーム４１をブレード４２の受風面積が大きくなる方向に向かって付勢する付勢部材ＳＰとを備えている。【選択図】図２
