[0005]

[Action]

 A printed circuit board with a luminous body that illuminates the lens wall of the wind body pivotally supported on the front side of the wind turbine base and illuminates the lens wall of the wind body is attached to the wind turbine base and its rear part in a detachable manner. It is housed between the substrate holder and the substrate holder, and is attached to the wind turbine base in a state of being held by the substrate holder. Further, the transmission characteristics when the light of the light emitting body passes through the lens wall are partially changed by the unevenness formed on the lens wall.

[0006]

[Effect of device]

 Since the present invention is configured as described above, the printed circuit board can be attached to the wind turbine base plate with one touch by simply sandwiching the printed circuit board between the wind turbine base plate and the substrate holder and connecting the substrate holder to the wind turbine base plate. It is possible to assemble, and the mounting structure of the printed circuit board can be simplified to simplify the work of assembling the printed circuit board on the wind turbine base, and the entire assembly of the pachinko ball wind turbine can be simplified. In addition, since the unevenness that changes the light transmission characteristics is formed on the lens wall of the wind car body, it is possible to change the brightness of the light that passes through the lens wall and is irradiated in a complicated manner, and it is possible to obtain various brightness values. Since the wind car body rotates in a state where the transmitted light is mixed, it is possible to enhance the luminous decoration effect of the wind car body when the wind car body rotates.
