That is, the slip ring 449 is formed of a rotor structure, and the slip cover 449c serves as a stator, so that power can be transmitted to the slip cover 449c even in a state where the slip ring 449 rotates .

In this state, while the electrode rings 449b rotate, the electric current continues to move to the slip cover 449c to maintain power supply to the external power storage device or transmission line.

The lower part of the slip cover 449c is coupled with an external cable connected to the outside, and the external cable is formed to extend outwardly from the bottom cover 444.

Therefore, when the direction motor 445 is driven, the cover 441 closely contacting the fixed plate 460 and the fixed plate 460 are simultaneously rotated, but at the same time, the cable 448 and the electrode rings 449b rotate together, 449 to prevent the external cable from tangling due to the rotation of the light collecting part 600.
