Patent abstract
A wind turbine generator tower is configured by arranging and connecting a plurality of approximately cylindrical tower sections in their axial direction. Each of the tower sections includes an approximately cylindrical tower section main body, and a plurality of approximately flat-plate protruding parts that are formed so as to protrude along the axial direction at at least an axis-wise end portion of the tower section main body on an outer circumferential surface and/or an inner circumferential surface of the tower section main body. The plurality of tower sections are connected when the protruding parts of one of the tower sections and the protruding parts of another one of the tower sections are friction-jointed with fastening means.
