PROBLEM TO BE SOLVED: To provide a rain shutter door capable of restraining outside air from flowing into a window side through a case covering a wound part of a shutter plate.SOLUTION: A rain shutter door includes a closing roller 11 and a movement-allowable support part 12. The closing roller 11 is brought into contact with a shutter plate 21 near a wound part 22 and rotated by an opening/closing operation of the shutter plate 21. Additionally, the movement-allowable support part 12 supports the closing roller 11, and allows the closing roller 11 to move following a positional change of the shutter plate 21 near the wound part, which is associated with the enlargement and reduction of a diameter of the wound part 22. |
