``Problems to be solved by the invention'' However, in such conventional technology, the branch lines of the curtain member are simply guided by the rails, so they do not have the function of maintaining their position or state by themselves, and the branch lines of the curtain member are simply guided by the rail. Even if it was fully expanded, it was difficult to tighten it sufficiently, and even if it did sag, it was unsightly.

The present invention has been made by focusing on such conventional problems.It is an object of the present invention to provide a sun shade device that is tightly stretched to prevent wrinkles when the shade cloth is fully opened, and has a good appearance quality without sagging. It is an object.

``Means for Solving the Problems'' The gist of the present invention to achieve the above purpose is that, in a sunshade device in which the opening is opened and closed using a foldable shade cloth, mutually disposed on both sides of the opening disposing rails having guide grooves facing each other, movably fitting the guided elements into the guide grooves of each rail, and forming a chain by sequentially connecting the guided elements with link members on each rail, Connection points of corresponding link members on both rails,
or in the vicinity thereof, a movable rod is constructed, and a rear end connecting member is constructed at a rear position corresponding to the end of the shade cloth with both ends movably fitted in the guide groove, so that the chains are connected to each other. Key points of the shade cloth are connected to the moving rod so as to close the opening when the shade cloth is unfolded while being guided by the rails, and the ends of the shade cloth are connected to the end connecting member, so that the chain is stretched and the shade cloth is fully opened. The sunshade device is characterized in that it is provided with a tensioning mechanism that pulls the end connecting member rearward and stretches the developed shade cloth when the sunshade cloth is opened.

``Operation'' When the chain is extended and moved within the rail to close the opening, the guided element moves within the guide groove of the rail, the link member extends, and the shade cloth is expanded by the moving rod.

When the chain is fully extended and the shaded cloth is expanded to its full opening, the tensioning mechanism pulls the end connecting member disposed further rearward adjacent to the end of the chain rearward, thereby tensioning the shaded cloth.

When the chain is moved in the closing direction, the tensioning mechanism stops working, and when the chain is moved further, the opening is finally fully opened.
