<P>PROBLEM TO BE SOLVED: To provide a wind power generation device capable of efficiently generating electric power without permitting the rotation efficiency of a windmill to be lowered by distortion or bending of a shaft during installation. <P>SOLUTION: A straight blade and vertical shaft type windmill for converting wind energy into rotational kinetic energy is comprised of a plurality of windmills 300. The plurality of windmills 300 are arranged in a stacked manner along the shaft 400 vertically provided. An upper support mechanism 610a, an intermediate support mechanism 610b and a lower support mechanism 610c provided between the shaft 300 and a main pillar 200 are arranged on a holding plate 210a, a holding plate 210b and a holding plate 210c. The upper support mechanism 610a, the intermediate support mechanism 610b and the lower support mechanism 610c can rotatably support the shaft 400 even when the shaft is inclined by a predetermined amount. <P>COPYRIGHT: (C)2007,JPO&INPIT |
