<p>A wind mill equipment rotated by wind power, characterized in that, to efficiently provide a rotating energy without being affected by wind direction, first the inner peripheral surface shape of each of three blades in cross section is formed such that meets the requirement of r = (r1 - r2) x ((t - 2π/3) x 2)/(2π/3) x 2 + r2 where an outermost radius as a distance between the position of each blade apart farthest from the center of a vertical axis and the vertical axis is (r1), an innermost radius as a distance between the position of each blade nearest the vertical axis and the vertical axis is (r2), the angle (rad) of any position (r) of each blade on the inner peripheral surface in cross section using, as a reference, a line connecting the position apart farthest from the vertical axis to the vertical axis is (t) (provided that 0 < = t < = 2π/3), second a non-rotated fixed guide fin is provided on the outer periphery of the wind mill equipment, and third wind introduced along the blades can be escaped smoothly to the outside of a wind mill without being whirled.</p> |
