[Effect of the invention]

Since the present invention is configured as described above, the cushioning material at the insertion end of the seat plate is positively utilized to seal the guide rail between the guide rail and the insertion end inserted loosely into the guide rail. While the double-sided guide rail sealant is also used, the relationship between the insertion end of the seat plate and the cushioning material must be such that the cushioning material always fits within the front-rear width of the insertion end and the shutter curtain is closed. Occasionally, the front and rear ends of the compressed cushion material can be inscribed in contact with the guide rails by the closing load obtained with this, so that the shutter curtain can be closed without increasing the opening and closing resistance of the shutter curtain. As a result, the guide rail can be used as a sealing material for the guide rail. The three functions as a sealing material for the guide rail for stopping can be performed simply and reliably at the same time, and the lower part of the shutter curtain and the opening frame are preferably used by using a shutter sealed with a sealing material. It is possible to provide a shutter lower sealing device that can be sealed to ensure high airtightness and sound insulation.
