A fitting metal of a different body in which screw holes are drilled in an opposing or adjoining face to the face on which the slit aperture is provided, is fitted to the rib of a T cross-sectional shape, which is formed in an inner circumference section of the extrusion molding frame member of a resin material or a metal material, and an object is attached to the fitting metal with screws by unitedly hooking the frame member and the fitting metal.
