Document Type and Number:
Japanese Patent JP6837468
Kind Code:
B2
Abstract:
To provide a vertical shaft rotor high in rotation efficiency even at low speed, and a vertically long blade thereof.SOLUTION: At the tip of a support arm that is fixed to a vertical main shaft connected to a power generator and projects in a radial direction of an intermediate attachment member, each main part of a plurality of lift type vertically long blades is fixed. In upper and lower parts of each main part, upper and lower inward arc bending parts that bend the tip in a vertical main axis direction are formed continuously. The chord length of the vertically long blade is the same length as a whole. Front edges of the upper and lower inward arc bending parts gradually increase an angle of elevation from a boundary with the main part to the tip parts of the upper and lower inward arc bending parts as they approach the vertical main shaft.SELECTED DRAWING: Figure 1
