PROBLEM TO BE SOLVED: To provide a frame member attaining a framework in manufacturing a louver blade adapted with 100% compatibility to a louver window of industry specifications comprising a louver support for 6.0-6.8 mm, with sufficient strength with the framework based on screw fastening, and a method for manufacturing the frame member, and a framework structure.SOLUTION: The frame member for constituting the louver blade framed by screw-fastening upper and lower lateral frame members and right and left vertical frame members to the edges of a plate glass, is formed by uniting a screw hole part and a body part which are manufactured separately from each other. Only the screw hole part projects by a combined portion when fitted into a groove of a mating frame member, in the length direction from the body part of the frame member, and the body part of the frame member does not project. The screw hole part is shaped to have a width settled into the groove of the body part and to be opened at both ends. |
