LIFT TYPE VERTICAL SHAFT WINDMILL

To provide a lift type vertical shaft windmill which inhibits a fluctuation range of an angle of attack of a movable blade which rotates according to a rotation speed from becoming excessive.SOLUTION: A lift type vertical shaft windmill includes: a power generation part; a rotary shaft which is integrated with the power generation part and rotates around a vertical axis; a plurality of windmill blades connected to the rotary shaft through arms 14 and rotate around the vertical axis; movable blades 15 each of which may rotate around an axis connecting the rotary shaft with the windmill blade; and excessive rotation inhibition guide bodies each of which causes the movable blade 15 to be inclined around the axis by action of a centrifugal force set according to a rotation speed of the rotary shaft. The lift type vertical shaft windmill includes: support shafts 30 each of which is integrated with the arm 14 and provided so as to be rotatable relative to the movable blade 15; and a damper mechanism 41 which generates reaction torque which counteracts a moment for causing the support shaft 30 and the movable blade 15 to rotate relative to each other.SELECTED DRAWING: Figure 3 【課題】回転速度に応じて回動する可動翼の迎角の変動幅が過大となることを抑制する揚力型垂直軸風車を提供すること。【解決手段】発電部と、発電部に一体化されかつ垂直軸周りに回転する回転軸と、回転軸にアーム１４を介して連結され垂直軸周りに回転する複数の風車翼と、回転軸と風車翼とを結ぶ軸線周りに回動可能な可動翼１５と、回転軸の回転速度に応じた遠心力の作用によって可動翼１５を軸線周りに傾斜させる過回転抑制誘導体とを備える揚力型垂直軸風車であって、アーム１４に一体化されかつ可動翼１５に相対回転可能に設けられた支持軸３０と、支持軸３０と可動翼１５とが相対回転するモーメントに対抗した反力トルクを発生させるダンパ機構４１とを備えている。【選択図】 図３
