Supporting both ends of the entire device (supporting one end of the wind turbine rotating shaft and supporting the generator) becomes easier, and since the height that protrudes upward in the exterior of the building can be reduced by the horizontal arrangement, the wind load is stabilized. You can take it. In addition, as described above, the height of the building exterior protruding upward can be reduced, so that the building appearance can be kept good, for example, when the building is arranged on the roof.

It is preferable to use a resistance type wind turbine as the vertical type wind turbine and arrange it so that the wind receiving surface above it receives the constant wind. In addition, in this configuration, vertical wind turbines may be arranged in a plurality of stages vertically, and an intermediate horizontal member may be interposed between adjacent wind turbines.

A resistance type wind turbine may be used, and the resistance type vertical wind turbines may be vertically arranged in a plurality of stages so that the wind receiving surfaces are adjacent to each other.

When a resistance type vertical wind turbine is used, it is preferable to provide a wall body for preventing constant wind from hitting the non-winding surface.

The vertical wind turbine may be arranged on a ridge with a pitched roof. In this configuration, it is preferable to arrange the roof member above the vertical wind turbine.

The vertical wind turbine may be arranged on a non-tilted roof. Further, the vertical wind turbine may be arranged on the parapet or on the balcony waist wall. In such a configuration, it is preferable to dispose the shade member or the handrail member above the vertical wind turbine. A solar power generation device is preferably attached to the upper surface of the roof member, the shade member, or the handrail member described above. Moreover, it is preferable that the lower surface side of the roof member, the shade member, or the handrail member has a convex shape.
