PROBLEM TO BE SOLVED: To provide a daylighting device for enabling independent lifting of an inner light shelf and a sunlight shielding device that are suspended and supported so as to be lifted along mutually overlapping lifting orbits and allowing easy installation of the inner light shelf and the sunlight shielding device.SOLUTION: A daylighting device has an inner light shelf that is arranged in an upper area of an indoor window surface and allows external light to enter a room by reflecting external light using at least one plate, and a sunlight shielding device capable of adjusting a daylighting amount by lifting sunlight shielding members suspended and supported below the inner light shelf. A winder 5 from which sunlight shielding members 8 are suspended and supported is installed in a head box 1 from which plates 3a to 3f are suspended and supported, the sunlight shielding members 8 are suspended and supported from cords 6, 7 hanging down from the winder 5 below the plates 3a to 3f, and the plates 3a to 3f have through holes to allow insertion of the cords 6, 7. |
