この考案は、車外の水が換気ダクトを通つて車
内に入ろうとするのを効果的に防止するようにし
た自動車用換気装置における防水構造に関する。[Detailed description of the invention] (Field of industrial application) This invention relates to a waterproof structure for an automobile ventilation system that effectively prevents water from outside the car from entering the car through the ventilation duct. .
（従来の技術）
自動車には、通常、車室を換気するための換気
装置が設けられる。(Prior Art) Automobiles are usually provided with a ventilation system for ventilating the passenger compartment.

れる。 The above-mentioned ventilation device includes, for example, one shown in Japanese Utility Model Application Publication No. 50-6041. That is, in this configuration, a through hole is formed in the outer panel of the vehicle body, and a ventilation duct is provided so as to pass through the through hole. This ventilation duct communicates the inside and outside of the vehicle body, and a flange is formed at the edge of the opening on the outside of the vehicle. This flange is then screwed onto the opening edge of the through hole. Further, a louver is attached to the exterior surface of the vehicle body to cover the vehicle exterior opening and flange of the ventilation duct.

る。 In the above configuration, it is desirable that the outer surface of the vehicle body be formed as smooth as possible from the viewpoint of appearance. Therefore, the louver is formed relatively close to the opening of the ventilation duct on the outside of the vehicle so as to prevent the louver from protruding from the outside surface of the vehicle body. On the other hand, recently, ventilation ducts are sometimes made of resin. In this case, if you want to firmly support the ventilation duct against the outer skin of the vehicle body, it will be necessary to provide a retainer that holds the flange of the ventilation duct between the opening edge of the through hole and the flange of the ventilation duct. .

る。(Problem to be solved by the invention) By the way, in the case of the above structure, if the opening on the outside of the ventilation duct and the louver are formed so as to be close to each other, and in addition, a retainer as described above is provided between the two. , the inner hole of this retainer and the louver will come very close to each other. For this reason, for example, when washing a car, when water is poured vigorously onto the car body, the water that has passed through the louver is guided into the inner hole of the retainer and tends to flow into the ventilation duct. There is a risk that it will fall into place.

る。(Effects of the invention) According to this invention, the outside opening of the ventilation duct is covered with double louvers, so when water from outside the car tries to flow into the ventilation duct through these louvers during a car wash, for example, this water is can be more accurately guided in the desired direction by these louvers. Therefore, water is effectively prevented from entering the vehicle interior through the ventilation duct. Moreover, in this case, since the louvers are double-layered, the direction of water scattering from outside the vehicle to the inside of the ventilation duct can be easily reversed, increasing the degree of freedom in guiding water. Waterproofing effect is enhanced.
Furthermore, since one of the two louvers is formed by effectively utilizing a retainer for supporting the flange of the ventilation duct, it can be simply constructed even if the louvers are doubled as described above.
