Abstract

Improved thermal insulation of opening devices. [Solution] The structure comprises a frame 6, a surface material 8, and an edge material 9. The frame 6 includes a metal frame 10 having a hollow section and a resin frame 11 located on the indoor side of the metal frame 10 and having a hollow section 46. A reinforcement 12 is provided within the hollow section 46 of the resin frame 11. The surface material 8 covers the visible surface of the frame 6 and is bent along the depth surface of the frame 6. The edge material 9 is attached to the depth surface, with the bent portion 13 of the surface material 8 sandwiched between the edge material 9 and the frame 6, and fixed with a screw 14 that is screwed into the reinforcement 12 from the outer circumference.
