The present invention has been proposed to improve the problems in the prior art, and an object of the present invention is to enable convenient and efficient use of the air signboard only by operating the power switch without an inconvenient process before and after the use of the conventional air signboard. The present invention for achieving the above object constitutes a bulkhead panel with a hole formed in the body inside the lower case to separate the space up and down, and a winding part for winding the tube body at the lower end of the bulkhead panel, and the upper part of the lower case is a tube When the main body is folded, it constitutes a cover that automatically covers the case. The air signboard of the present invention shows the effect that the roll type storage and automatic installation can be made by the internal winding unit only by operating the power switch, so that the management can be made more easily. As a result, the air signboard is used only when necessary. This prevents unnecessary power wastage and allows the product to be used for a long time without any trouble due to easy maintenance, thereby saving costs. There is this.
