<P>PROBLEM TO BE SOLVED: To provide a windmill apparatus for a wind power generator, which includes a blade member that has an optimal shape or mass for utilizing energy of wind power being movement of air having a small mass to a maximum without uselessness, and that can avoid noise and damage caused by magnitude of a velocity of the wind, and which has an optimal configuration for wind collection. <P>SOLUTION: The windmill apparatus includes: a rotary shaft 2 which is supported to be freely rotatable by support frames 1, 1; three blade members 3, 3, 3 in a tapered rectangular plate shape which are fixed at their one side, to the rotary shaft at a fixed angle interval of 120° alternately, and each of which has elasticity and becomes thin toward an outer end; a blade cover 4 which covers an upside of the three blade members 3, 3, 3 within a turning range; and connection means 5 which are provided in both ends of the rotary shaft 2 and can be directly or indirectly connected with a rotary shaft 2 of a windmill apparatus or with a rotary shaft of a power generator for another wind power generator. <P>COPYRIGHT: (C)2013,JPO&INPIT |
