PROBLEM TO BE SOLVED: To provide a louver device which can guide solar radiation to the window side and the deep side of a ceiling in a room while suppressing glare.SOLUTION: A louver device comprises: a plurality of reflective fins which reflect sunlight to a ceiling inside a building; a plurality of shading fins which are arranged below the reflective fins to shade sunlight; and turning means which turns the reflective fins and the shading fins in the vertical direction. Each of the shading fins is turnably journaled and formed in an approximately dog leg shape in a cross section view. Each of the reflective fins is configured to include two members consisting of a turning part and a fixed part. The turning part has an upper surface and a front surface, and the upper surface of the fixed part is inclined upward toward the building side. The turning means turns the plurality of shading fins in the vertical direction in the same phase, and turns the plurality of turning parts in the vertical direction in synchronization with the shading fins. |
