Abstract
The fusion of a side wall may be made difficult by using a fusion-resistant material having light weight. Provided is a casing including a side wall having a multi-layer structure. In the casing, the side wall includes an outer wall, a fusion-resistant material provided at an inner side of the outer wall with a predetermined gap with respect to the outer wall, and an inner wall provided at an inner side of the fusion-resistant material with a predetermined gap with respect to the fusion-resistant material.
Claims14
A casing, comprising:
- a side wall having a multi-layer structure, and including:
- an outer wall, and
- a sheet of fusion-resistant material provided substantially throughout an entire inner side of the outer wall, and having opposing first and second surfaces, the first surface facing the outer wall, and being separated from the outer wall by a gap over its entire area, the fusion-resistant material having a bent configuration so that the first surface has alternating projection portions and dent portions which face the outer wall, with a distance from the outer wall to the first surface of the fusion-resistant material at the respective dent portions being greater than a distance from the user to the first surface of the fusion-resistant material at the respective projection portions.
