PROBLEM TO BE SOLVED: To provide an opening structure having a good look from an indoor side capable of mounting window curtains such as a curtain or the like on the indoor side by storing a face grid in an opening frame, obtaining the sufficient spaciousness for making the maximum effective use of the open limit of a window without causing an obstacle to a passer-by outside the window, having an advantage in terms of strength because the face grid has such a structure that it is not largely projected from the window even if the window is opened toward the outdoor side without impairing beauty around the window in terms of an external appearance by making the opening structure as the one providing the face grid on the indoor side of the window provided to the opening frame. SOLUTION: The window bar 5 is provided inside an opening frame of a wooden frame 3 on the indoor side B of a window of a building. COPYRIGHT: (C)2004,JPO&NCIPI
