It consists of a screen that is pulled out from the take-up box and can be opened and closed by rotating the take-up shaft, and a guide rail that guides the edge of the screen in a retaining state when the screen is opened and closed. It is installed and used.

However, when the roll screen device is attached to the opening, the roll screen device may be fixed to the inner surface portion of the opening or fixed to the wall portion around the opening depending on the situation of the installation location. In many cases, one of the left and right guide rails must be fixed to the inner surface of the opening, and the other to the wall surface, depending on the site conditions. As a result, the installation work was very troublesome. Moreover, since the guide rail in the conventional roll screen device is directly fixed to the opening with a screw, it is very difficult or impossible to attach the guide rail depending on the shape of the opening. In some cases, therefore, handling guide rails was particularly troublesome, such as having to confirm the site in advance and then send the product suitable for that site.
