PURPOSE:To provide an apparatus capable of supplying the sunlight to a place where the sun does not stream in general by introducing the sunlight collected from two reflective surface units capable of freely changing the angle of depression and the angle of elevation through a narrow and plane rectangular opening part. CONSTITUTION:The first reflective surface unit 1 and the second reflective surface unit 5 are monolithically supported so that the angles of depression and elevation may be changed and a narrow opening part 9 is made along the support shaft 4 of the reflective surface units in a space to introduce the sunlight. The angles of depression and elevation of the reflective surface units are changed according to movement of the sun and the collected sunlight is introduced through the opening part.
