 By the way, in the above-mentioned configuration, due to a dimensional error or an assembly error of the casing seal member F, as shown in FIGS. 9 and 10, the end portion of the casing seal member F and the electrical component seal member G are separated from each other. It is unavoidable that there is a gap in the. Therefore, the sealing agent is injected into the gap to keep the inside and outside of the housing sealed.However, if the sealing agent squeezes out during assembly, the appearance of the casing will be contaminated, and this will significantly reduce the product's appearance. There is an inconvenience that leads to quality deterioration. In order to eliminate the above-mentioned inconvenience, it is possible to integrally form the casing seal member Hf and the electric component seal member Hg at the time of manufacturing, as in the seal member H shown in FIGS. 11 and 12. However, as is clear from the figure, since both seal members Hf and Hg are developed along the planes that are substantially orthogonal to each other, an extremely complicated mold device is required to perform integral molding. Therefore, there is an inconvenience that causes a significant increase in manufacturing cost. In view of the above situation, an object of the present invention is to provide a seal member for an electronic device capable of reliably sealing the inside and outside of the casing without lowering the quality of the electronic device and increasing the manufacturing cost. To do.

[Means for Solving the Problems]

 Therefore, in the present invention, the casing seal portion interposed at the meeting portion between the one casing and the other casing is formed integrally with the casing seal portion such that the casing seal portion is developed on the same plane as the casing seal portion. A seal member that seals the inside and outside of the electronic device casing from the electrical component seal portion that is interposed between the electrical component and the edge of the through hole by being twisted with respect to the casing seal portion during assembly is constructed. By accomplishing the above, the above object was achieved.

[0005]

[Action]

 According to the above configuration, since the casing seal portion and the electric component seal portion are integrally molded with each other, no inadvertent gap is created, and thus the seal inside and outside the equipment casing can be maintained without using a sealing material. In addition, since the casing seal portion and the electric component seal portion are spread on the same plane, the above-mentioned seal member can be easily manufactured by a simple mold which is divided into upper and lower parts.
