設けられた吸気バイパス通路である。1 and 2 show a first embodiment of the present invention. In the figure,
Reference numeral 11 is an inlet base of the air cleaner, 12 is an intake port provided at a substantially central portion of one side surface of the inlet base 11 together with a vehicle body outer plate 17, 13 is another side surface of the inlet base 11, and a lower edge of the intake port 12 is provided. An air cleaner communication passage provided at a position higher than 12a, 14 an air / water separating plate provided in the inlet base 11, 15 an intake passage provided under the air / water separating plate 14, 16 a drain hose, and Reference numeral 18 denotes an intake bypass passage which is provided above the air / water separating plate 14 and above the upper edge of the intake port 12.
前記気水分離板14は平板状に形成されていて、インレッ

リーナ連通路13の間を遮閉するように下端14aが吸気口1
2の下縁12aより下方に垂設されている。そして、該気水
分離板14の下端とインレットベース11の下面との間の隙
間が吸気通路15になっている。The air / water separating plate 14 is formed in a flat plate shape, and has a lower end 14a from the upper surface to the lower surface of the inlet base 11 so as to block the space between the intake port 12 and the air cleaner communication passage 13.
2 is provided below the lower edge 12a. The gap between the lower end of the water / water separating plate 14 and the lower surface of the inlet base 11 serves as an intake passage 15.
第１実施例のインレットベース11は上記のような構成で

できる。Since the inlet base 11 of the first embodiment is constructed as described above, the water (water droplets) that has entered through the intake port 12 of the vehicle body outer plate.
Hits the air / water separating plate 14 and falls downward, and the drain hose 16
Is discharged from the vehicle to the outside of the vehicle, and only air is
It is sent to the 13 side. Then, even if the drain hose 16 becomes clogged with water and the intake passage 15 provided at the lower portion of the air / water separating plate 14 is closed, the air is still above the water / water separating plate 14. It is sent to the air cleaner communication passage 13 side from the intake bypass passage 18 provided in the above to prevent stalling and the like. Further, since the invaded water overflows from the lower edge 12a of the intake port 12 and the water level does not reach above the lower edge 12a, the water can be prevented from entering the air cleaner communication passage 13.

てしまうのを可及的に防止するようになっている。3 to 4 show a second embodiment of the present invention. In this embodiment, the upper portion of the steam / water separating plate 14 is bent into an L shape so that the intake port 12
A horizontal bent portion 19 extending toward one side surface of the inlet base 11 and a vertical bent portion 20 extending toward the upper surface of the inlet base 11 are formed, and the intake bypass passage 18 is formed in the vertical bent portion 20. By providing the above, it is possible to prevent water droplets sucked from the intake port 12 from being directly sent from the intake bypass passage 18 to the air cleaner communication passage 13 side without hitting the air / water separation plate 14. Has become.

っている。7 to 8 show a fourth embodiment of the present invention, in which the intake bypass passage 18 is provided with a one-way valve 21 which opens when a wind pressure of a predetermined pressure or more is applied. . The one-way valve 21 normally closes the intake bypass passage 18, and when the intake passage 13 is closed and the wind pressure applied to the one-way valve 21 rises, the intake bypass passage 18 is opened to direct air to the air cleaner communication passage 13 side. I am supposed to send it.

発明の効果 本発明は以上、説明したような構成のエアクリーナのイ
ンレットベースであるので次に述べるような効果があ
る。EFFECTS OF THE INVENTION Since the present invention is the inlet base of the air cleaner having the above-described structure, it has the following effects.
（１）インレットベース11内に水が溜まるなどして吸気
通路15が塞がれた場合でも、吸気バイパス通路18から空
気がエアクリーナ連通路13側に送られるのでエンスト等
を未然に防止することができる。(1) Even if the intake passage 15 is blocked due to water accumulated in the inlet base 11, air is sent from the intake bypass passage 18 to the air cleaner communication passage 13 side, so that stalling can be prevented in advance. it can.
（２）吸気バイパス通路18を吸気口12の上縁よりも上方
位置に設けたので吸気口12から侵入した水が空気に対し
て質量が大きく落下し易いため、吸気バイパス通路に到
達しにくく、かつ、気水分離板14の下端14aを吸気口12
の下縁12aより下方に垂設したので吸気口12から侵入し
た水が直接、エアクリーナ連通路に送られず気水分離板
14の気水分離効果を損なうことがない。(2) Since the intake bypass passage 18 is provided at a position higher than the upper edge of the intake port 12, the water that has entered from the intake port 12 has a large mass with respect to the air and easily falls, so that it is difficult to reach the intake bypass passage. In addition, the lower end 14a of the water / water separating plate 14 is connected to the intake port 12
Since it hangs downward from the lower edge 12a, the water that has entered from the intake port 12 is not directly sent to the air cleaner communication passage, but the air-water separation plate
It does not impair the air / water separation effect of 14.
（３）吸気口の下縁をエアクリーナ連通路よりも下方に
配置したので、吸気通路に溜まった水は吸気口から外部
に排出され、エアクリーナ側に侵入するのを防止するこ
とができる。(3) Since the lower edge of the intake port is arranged below the air cleaner communication passage, it is possible to prevent the water accumulated in the intake passage from being discharged to the outside from the intake port and entering the air cleaner side.
