<P>PROBLEM TO BE SOLVED: To provide a vertical shaft windmill suppressing aerodynamic resistance generated by the rotating speed increase of the windmill and easily and rapidly changeable in the number and shape of blades according to the magnitude of wind force. <P>SOLUTION: The vertical shaft windmill has a rotating shaft 1 extended in a vertical direction, a plurality of blades extended in the vertical direction, and support members 3, 3A, 3B, 3E for supporting the blades 2 to the rotating shaft 1. The support members 3, 3A, 3B, 3E are formed in plate shape, and the peripheral edge parts of the support members 3, 3A, 3B, 3E of plate shape are projected in a direction of the rotating shaft (to form rim-like members 3b). The blades are attachable to and detachable from the peripheral edge parts (the rim-like members 3b) of the support members. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
