。After placing the top and bottom plates 1 and the body plate 2 with the flange part 1b of the top and bottom plate 1 on the flange part 2a of the body plate 2 as shown in FIG. 1, the flange part 1b of the top and bottom plate 1 is deformed downward. At the same time, the falling portion 1c of the top and bottom plate 1 is deformed inward to obtain the state shown in FIG. By deforming this overlapping portion downward, the free end portions of the top and bottom plates 1 and the body plate 2 are overlapped, as shown in FIG.

折曲げ部が夫々重なって挾持されるものである。This overlapping part is formed between the flange part 1b of the top and bottom plate 1 and the body plate 2, or the double bent part of the falling part 1c and the curled part 1d of the top and bottom plate 1, or the overlapped part between the flange part 2a and the curled part 2b of the body plate 2. The double bent portions overlap and are held together.
この場合、夫々の２重折曲げ部は折曲げ支点Ｃ−Ｅが上
下に位置することになる。In this case, the bending fulcrums C-E of each double bending portion are located above and below.

An inwardly curled portion 1d is formed at the tip of c, and on the other hand,
Flange portion 2a extending horizontally outward from the upper end of the body plate 2
A curled portion 2b is formed downward in the top and bottom plates, and after overlapping the flange portion 1b of the top and bottom plate 1 and the flange portion 2a of the body plate 2, the flange portion 1b of the top and bottom plate 1 and the flange portion 2a of the body plate 2 are assembled. is deformed, and between the flange part 1b of the top and bottom plate 1 and the body plate 2, the flange part 2a of the body plate 2, its curled part 2b, the curled part 1d of the top and bottom plate 1, and its falling part 1c overlap in this order. By holding the top and bottom plate 1 in this way, the falling part 1c
This falling portion 1 with the lower end E of the curved portion 1d as a fulcrum
a springback action in which the flange part 2a and the curled part 1d of the body plate 2 try to open, and a springback action in which the flange part 2a and the curled part 2b of the body plate 2 try to open using the upper end C of the flange part 2a and the curled part 2b as a fulcrum. As a result, the curled portions 1d and 2b act to press each other toward the contact surface F, and twice the pressing force (springback force) is applied to this contact surface.
従って、天地板１と胴板２との重合部の気密を完全に保
持できるものである。Therefore, the overlapping portion between the top and bottom plates 1 and the body plate 2 can be completely kept airtight.
