Abstract
Wind mill blades are mounted on spokes provided on a power shaft via springs, and thereby in an ordinary wind velocity the wind mill blades are adjusted into a prescribed angle, while in a storm they are made parallel to the direction of a wind, thus enabling the wind mill blades, etc., to be prevented from being damaged and the wind mill blades to be large-sized.
