ABSTRACT:
In a window attaching framework in a building, upper and lower windows are foldably connected together, and one or a plurality of dampers or arms are installed between at least either the upper window or the lower window and the window attaching framework. Such dampers or arms prevents the windows from rapidly moving downward when opened, making it possible to effect smooth opening and closing of the windows.
