The Natural lightings structure through a window of a building is provided to easily come the sunlight to the inside of building through the reflecting mirror by rotating the pinion gear engaged to the rack gear and rotating the reflecting gear with a predetermined angle. A structure for streaming sunlight through a window of a building is composed of a support body(300) formed with a horizontal penetration hole(310) at the center; a support rod(200) whose both ends are combined with the penetration hole; a reflecting mirror(120) horizontally formed with a combining hole(122); a pinion gear(600) mounted at both ends of the supporting rod; and a rack gear driving part(400) inserted with a rack gear(500) inside, exposed through a hole(414) mounted at one side, and engaged to the pinion gear to rotate the pinion gear to front and rear directions and to control a reflection angle of the reflecting mirror. |
