PURPOSE:To adjust the size of an interval by movably providing an air condition adjusting plate, and moving this air condition adjusting plate. CONSTITUTION:A slit 12 is formed along the width of an installation plate part 14 of an air condition adjusting plate 13, and in installing the air condition adjusting plate 13 to a main reflection plate 11, a face screw 17 is loosened, while its position is adjusting along the width of the main reflection plate 11. When only a small return air quantity for air conditioning is required, the air conditioning plate 13 is installed on the center side of the main reflection plate 11 to set an interval of a ventillation part 34 small. For setting the air quantity large, the face screw 17 is tightened and fixed with the air condition adjusting plate 13 expanded toward the outer side of the main reflection plate 11 to set the interval of the ventillation part 34 large. The size of the interval can thus be changed easily corresponding to the need of an installation position. |
