上するという効果がある。As is apparent from the above description, according to the vacuum double structure according to claims 1 to 3 of the present invention,
Instead of connecting by TIG welding as in the conventional example, the constituent members themselves of the vacuum double structure are formed by curling, or the constituent members are connected and integrated by curling. Therefore, the constituent members can be formed in a shorter time than in the conventional example, or the constituent members can be connected and integrated with each other, resulting in high productivity. Moreover, since it is not necessary to use argon gas or the like as in TIG welding, the production cost is reduced. Further, since the joined curling flange portions are integrally curled and mechanically connected to each other, even constituent members having different materials or different thicknesses can be easily connected and integrated. Further, unlike the conventional example, it is not one in which a part of the constituent members are melted to be joined and integrated, so that there are few defective products and there is an effect that the finish is beautiful. Further, according to the third aspect, since the sealing material is interposed between the curling flange portions, there is an effect that the sealing property is further improved.
