However, in the above-mentioned conventional roll screen apparatus, when the screen is subjected to external force such as wind pressure, for example, the screen is slackened, resulting in poor appearance and slackness. When the screen is wound up with the occurrence of wrinkles, a wrinkle is formed on the screen.

[0006] The slack of the screen is caused particularly when the size of the screen is large, when the screen is a mesh screen, or when the screen is installed in an opening so as to be curved along a curved guide rail during opening and closing. Then, it easily occurs even when no external force acts.

Further, in the conventional configuration, it is conceivable to tighten the screen in order to eliminate the slack. However, if the screen is tightened between the guide rails, there is a possibility that the opening and closing operation of the screen cannot be performed smoothly. Therefore, extremely accurate precision is required for the dimensions of the screen, the mounting dimensions of the guide rails, and the mounting dimensions of the locking members, which makes production and construction difficult and increases costs.
