PURPOSE: To improve sealing performance between a central panel and a skin supporting the central panel at a proper place by enabling usage of plural glass panels, and to improve heat insulating effect of an assembly and its appearance by composing an inner skin and an outer skin in the same structure. CONSTITUTION: A first skin 16 and a second skin 16' are the same, so they are molded in the same die, and each includes an outer edge 22, 22' having a flange 26, 26', a panel part 23, 23', and an inner edge 24, 24' forming an opening part in which a central panel 12 is inserted. Next, the flanges 26, 26' respectively have cut parts 28, 28' at their open ends to be jointed together, and each skin 16, 16' is provided with a second flange 30, 30' inwardly extended toward the opponent skin 16, 16'. Next, a foam polyurethane heat insulating core 20 is introduced into a cavity 32. The central panel 12 comprises two glass panels 36 substantially in parallel to each other having an interval, and a drying agent holder 38 to hold drying agent substance 40 which is provided with a slot 42 is provided between them. Each groove 43 has a sealing piece 45 comprising sealing material of rubber or similar material to that to prohibit invasion of moisture into a gap between the glass panels 36. |
