<P>PROBLEM TO BE SOLVED: To provide a wind mill for a horizontal axis type wind power generator, in which a wind speed range where power generation can be performed by increasing rotating torque even in a low wind speed is enlarged, and which can be mass-produced at low cost. <P>SOLUTION: The wind mill for a horizontal axis type wind power generator has a rotating shaft in an approximately wind force direction, and is constituted by radially connecting a plurality of blades to the rotating shaft through a connection member. In the wind mill, wind receiving faces of the blades are formed in such a manner that base end sides thereof are rectangular blade parts of an aspect ratio of 1.5 or more, and delta blade parts of an aspect ratio of 1.5 or less are connected to the outside of the rectangular blade parts. A twist angle of 10 to 20 degrees is set between both side parts of the rectangular blade part, and the delta blade parts is in a flat shape. <P>COPYRIGHT: (C)2004,JPO |
