PROBLEM TO BE SOLVED: To provide a wind power generation device which has favorable power generation efficiency and is excellent in an icing/snow-sticking prevention property at a windmill portion, particularly, at a portion of a low circumferential speed such as a root of a windmill blade or a hub.SOLUTION: A wind power generation device includes: a plurality of windmill blades; a freely rotatable hub for fixing and supporting the windmill blades; and a generator which is driven by rotating the windmill blades and the hub. The wind power generation device is characterized in that icing/snow-sticking prevention processing is applied to at least the vicinity of portions of the windmill blades fixed to the hub and a surface of the hub. |
