To provide a high efficiency wind power generation apparatus which enables increase in the size and weight of a windmill supporting device and a column support to be suppressed thereby attaining cost reduction even when the size and weight of a windmill and a power generator are increased.
The wind power generation apparatus includes: a plurality of windmills having at least a front propeller windmill 3 rotated in a prescribed one direction and a rear propeller windmill 4 rotated in a direction reverse thereto, each of the windmills 3 and 4 having horizontal rotary shaft; a nacelle 2 in which the front and rear propeller windmills are arranged side by side in a wind receiving direction and rotatably supported and the horizontal rotary shafts of the respective windmills are coaxially disposed; a power generator disposed in the nacelle and rotationally driven by horizontal rotary shafts of the front and rear propeller windmills; and a tower 5 supporting the nacelle.
