In this figure, the same components as those already described are denoted by the same reference numerals, and the description thereof is omitted to limit the description to the different parts. The operation switch 2 is provided on the side surface portion of the second member 5.
The joint surface 5d is formed at a position corresponding to the joint surface 20a of 0, and these joint surfaces are joined by the vibration welding described above. The fourth member 51 has a total length L2 that is longer than the total length of the second member 5, and the other configurations are substantially the same as the second member.

Next, FIG. 4 is a cross-sectional view of an essential part showing a state in which the waterproof case is welded by the heat welding device 200. In this figure, the outer peripheral surface of the second member 5 is fixedly fixed by the fixing jig 202. It Further, after the first member 3 is held by a jig (not shown), the joint surfaces 3a, 5a are brought into contact with the heater 205 at about 200 ° C. and melted.

As a result of joining in this way, the joining surfaces are completely joined, but different molten states can be obtained, so that a so-called laminated structure is formed and the strength is increased. Similarly, the third member 6 forming the under-shaped portion A and the operation switch portion are also joined. In addition, in the above-mentioned embodiment, the application to the waterproof / underwater case of the video movie, the camera, etc. was able to secure the grade 7 or higher of the general rule of the waterproof test of the Japanese Industrial Standard. Further, the present invention is not limited to the above-described examples, and any material having an under-shaped portion at least on the joint surface can be applied, and the resin used can be appropriately selected according to the purpose of use. Of course, it can be applied to all industrial products.
