【産業上の利用分野】本発明は電子機器筐体における防
水構造に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure for an electronic equipment casing.

Description of the Related Art Conventionally, in order to waterproof an electronic device, an annular rubber molding which is not broken is sandwiched as a packing between upper and lower housing parts of a device housing, and this annular packing is used. A structure was used to prevent water droplets from entering through the gap between the upper and lower casings.
【０００３】この従来の防水構造によると、ゴムパッキ
ングが切れ目のない環状であるのでゴムパッキングを圧
縮成形又は射出成形により製造せざるを得なかった。According to this conventional waterproof structure, since the rubber packing has a continuous ring shape, the rubber packing has to be manufactured by compression molding or injection molding.
【０００４】しかしながら、ゴムパッキングを圧縮成
形、射出成形する際に用いられる金型は高価であり、ま
た、成形に要する時間も長いのでゴムパッキンの製造単
価は高いものにならざるを得なかった。However, the mold used for compression molding and injection molding of rubber packing is expensive, and the time required for molding is long, so that the manufacturing unit price of the rubber packing must be high.

雑となり、又、異なる形状、周囲長のゴムパッキングご
とに金型を製作しなければならないので、この点からも
ゴムパッキングの製造単価が高くなっていた。Further, it is necessary to use an annular rubber packing having a shape of the peripheral portion of the housing that requires rubber packing, a shape corresponding to the peripheral length, and a peripheral length. If the length is slightly different, it is necessary to prepare a different type of ring-shaped rubber packing, which complicates parts management, and molds must be manufactured for each different shape and perimeter rubber packing. From this point of view, the unit price of rubber packing was high.
【０００６】一方、筐体の変形や寸法誤差等により、
上，下の筐体部のパッキング押え部の一部に設計値より

グの反発力は、上，下の筐体部により小さな隙間程度に

い程度の大きさにする必要がある。On the other hand, due to deformation of the housing and dimensional error,
Assuming that a gap larger than the design value or a gap smaller than the design value may occur in a part of the packing holding part of the upper and lower housing parts, the packing holding amount can seal the gap larger than the design value. The repulsive force of the packing needs to be large enough not to deform the housing when the packing is compressed to a small gap by the upper and lower housing portions.
【０００７】従って、パッキングの押え量に対する反発

ると防水性を損う等の種々の問題がある。Therefore, the repulsive force with respect to the pressing amount of the packing needs to be adjusted to the minimum size required for waterproofing according to the case in which the packing is used, but in the annular packing, a cavity is formed inside. I can't make it,
This repulsive force can only be adjusted by reducing the contact area of the packing or changing the rubber hardness.
It was difficult to properly adjust the repulsive force. It is also possible to make the cross-sectional shape of the packing into a special shape such as a "U" shape, but the moldability of the packing is reduced.
There are various problems that it is necessary to form a wide groove on the side of the housing that receives the packing, and if the packing is twisted into the housing even if it is twisted a little, the waterproofness is impaired.

の問題が生じていた。As described above, in the conventional waterproof structure, since the continuous annular rubber packing is used as the packing, it is necessary to manufacture the packing by compression molding or injection molding. Is high, it is necessary to prepare packing that corresponds to the shape of the peripheral portion of the housing and the peripheral length, parts management becomes complicated, and it becomes difficult to set the repulsive force of the packing to an appropriate value. There was a problem.
