るといった問題がある。However, if the diameter of the breathing hole is increased, a large amount of rain or fog that causes rust will enter due to wind and rain. On the other hand, in order to reduce this, the hole diameter must be reduced. Then, there is a problem that external water droplets and humidity are required to be sucked from there due to the suction phenomenon accompanying the atmospheric pressure adjustment.
【０００４】そこで、本発明においては、良好な気圧調

FIG. 1 is a sectional side view of an embodiment of an outdoor device housing structure according to the present invention, and FIG. 2 is an enlarged sectional view of a main part. Referring to these drawings, a box-shaped casing 12 having a plurality of units 11 forming a main part of a wireless communication device is provided with a double structure substantially parallel to the bottom cover 14 on the lower side inside thereof. A partition plate 16 is provided.

る。The bottom cover 14 is provided with a relatively large breathing hole 18 so that smooth ventilation is possible, and at a position away from the breathing hole 18, a valve body 21 to be described later is normally closed. A drainage opening 23 is provided. The partition plate 16 is provided with ventilation holes 25 at positions that do not coincide with the breathing holes 18 of the bottom cover 14. Also, the partition plate 16
At a predetermined position on the lower surface side of the bottom cover 14 so as to block a line connecting the breathing hole 18 of the bottom cover 14 and the ventilation hole 25 of the partition plate 16 or along the line to draw rainwater (in FIG. 2, finely hatched). An inclined portion 27 (obstacle member) that is inclined is provided so that a portion such as a water drop) cannot linearly enter the inside. Therefore, due to the presence of the inclined portion 27, rainwater or the like that enters from the breathing hole 18 of the bottom cover 14 is not blocked by this and does not enter the substantial inside of the housing 12, and instead the inclined portion 27 is inclined. While moving along the portion 27, it falls near the drainage opening 23.

Are made of different members, and the upper portion 21a is made of a material having a smaller specific gravity than water (for convenience, floats on water), for example, styrofoam, and the lower portion 21b has a larger specific gravity than water (simple Is submerged in water). When a certain amount of rainwater or the like is accumulated near the valve body 21 (drainage opening 23), the buoyancy of the valve body upper portion 21a overcomes its own weight, whereby the valve body 21 moves to the upper side for drainage. The opening 23 will open. And
After being discharged to some extent, the drainage opening 23 closes. On the other hand, in normal times when rainwater etc. are not so accumulated,
The valve body 21 closes the drainage opening 23 by its own weight.
