PROBLEM TO BE SOLVED: To provide a wind power generation device that can effectively prevent snow from piling up at a top face of a nacelle and freezing by a simple configuration without using a special drive source.SOLUTION: In a wind power generation device provided with a rotor 4 in any of end parts in front or rear of a nacelle 2, a top face of the nacelle 2 has an angle shape in front view and, at the apex thereof, a piled up snow division plate 7 oriented in back and forth directions is erected so that snow to be piled up at the top face of the nacelle 2 is prevented from being combined in a hat-shape straddling over the top face of the nacelle 2, separated on both sides and falls.SELECTED DRAWING: Figure 1 【課題】特別の駆動源を用いることなく、簡単な構造で、ナセルの上面への積雪やその凍結を効果的に防止しうるようにした風力発電装置を提供する。【解決手段】ナセル２の前後いずれかの端部にロータ４を設けた風力発電装置において、ナセル２の上面を正面視山形とし、その頂部に前後方向を向く積雪分離板７を立設し、ナセル２の上面に堆積しようとする積雪は、ナセル２の頂部に跨がる笠状に結合されることはなく、両側方に分離して落下するようにする。【選択図】 図１
