A supporting body for supporting the lid body, wherein the supporting body is integrally provided with pivot shafts to be inserted into the curl portions of the lid body at both ends, and in the middle portion between the pivot shafts. Is provided with a stretchable portion for varying the distance between the stretchable portion 3 and the stretchable portion.
It consists of one or more thin-walled hinges.

[0007]

With this structure, it is only necessary to provide the lid with the curl portion at the peripheral edge, and it is not necessary to provide the bearing portion having a complicated shape. Therefore, it is possible to prevent the processing man-hours from increasing, and to improve the structure of the lid. It can be simplified. In addition, the support body attached to the opening edge of the main body case does not need a shaft made of hard steel wire because the pivot shafts to be inserted into the curl portion of the lid body are integrally provided at both ends. Thus, not only is there no need to worry about losing the shaft, but it is also possible to prevent the number of parts from increasing. In addition, by reducing the expansion and contraction part of the middle part of the support, the distance between the pivot shafts at both ends is narrowed, so each pivot shaft can be easily inserted into the curl part of the lid, and the support to the lid The body can be easily assembled.

According to a second aspect of the present invention, in the apparatus for attaching a lid, the expandable portion provided in the middle portion of the support body is formed with three or more thin hinges formed at predetermined intervals in the longitudinal direction of the support body. Since it is made up of two parts, it is possible to move the pivots of both ends of the support in parallel with each other, and it is easier to insert the pivots into the curl of the lid, and the workability of assembly is improved. Is improved.
