PROBLEM TO BE SOLVED: To provide a wind power generator enhanced in the cooling performance of control equipment installed in a hub.SOLUTION: In order to solve the aforementioned problem, a wind power generator according to the invention comprises: a rotor 2 having a hub 20 storing control equipment and a blade 1 supported by the hub 20; a nacelle 6 supporting the rotor 2 rotatably; and a rotary main shaft 3 arranged over in the hub and in the nacelle. There is formed a passage for communicating the inside of the hub and the inside of the nacelle. The passage is arranged in the radially outer side of the rotary main shaft and is fixed with respect to the nacelle. A passage in the hub is provided with a first melt-off pore.SELECTED DRAWING: Figure 2 【課題】ハブ内に設置した制御機器の冷却性能を高めた風力発電装置を提供する。【解決手段】上記の課題を解決するために、本発明に係る風力発電装置では、制御機器を収納したハブ２０及びハブ２０で支持されるブレード１を備えるロータ２と、ロータ２を回転可能に支持するナセル６と、ハブ内及びナセル内に渡って配置される回転主軸３を備え、ハブ内とナセル内を連通する流路が形成され、流路は回転主軸の径方向外側に配置されると共に、ナセルに対して固定されており、ハブ内における流路には第１の流出孔が設けられることを特徴とする。【選択図】 図２
