【考案の詳細な説明】
本考案は自動二輪車あるいは自動三輪車などのように、
シートの下方にエンジンを露出配置した車両におけるエ
ンジンの吸気装置に関するものである。[Detailed explanation of the invention] The invention is designed to
This invention relates to an engine intake system for a vehicle in which the engine is exposed below the seat.
この種の車両は、第1図に示すようにエンジン1および

ければならない。In this type of vehicle, as shown in Figure 1, the engine 1 and its attached air cleaner 2, etc. are located low in the vehicle body, and are also located between the front wheels 3 and rear wheels 4, so dirt that is thrown up while driving is a problem. Rainwater is easily sucked into the air cleaner 2, and the air cleaner element must be cleaned and replaced frequently.
そこで上記の不具合を防止するため、エアクリーナの吸
気口をシート5の直下に位置させることが行われている
。Therefore, in order to prevent the above-mentioned problems, the intake port of the air cleaner is positioned directly below the seat 5.

続箇所のシート性を向上することを目的とする。The present invention also has an air intake device of the type in which the intake port is placed directly below the seat, in particular, the seat 5 and the rear fender 6 that integrally covers the lower part of the seat 5 and the upper part of the wheels 4, and this is integrated into the vehicle body frame. This is an intake system for a vehicle that is installed on top of 7, and the intake system can be easily obtained, and
The purpose is to facilitate connection with the air intake port of an air cleaner and to improve the sheeting properties of the connection point.

An air cleaner connection port 9 is opened at a location corresponding to the bottom of the small space 8 of the rear fender 6, and an elastic seal ring 10 is fitted into the connection port 9.
弾性シール環10の下周縁は横断面逆り形の内向きリッ

いる。The seat 5 and the chassis 6 are integrated into the vehicle body frame 7.
When the elastic seal ring 10 is placed and fixed on the vehicle body frame 7 together with the engine 1, the elastic seal ring 10 fits around the air intake port 21 of the air cleaner 2, which has been previously attached to the vehicle body frame 7 together with the engine 1, so that its lip 101 tightly contacts the shoulder of the air intake port 21. It is configured.

影響がないようにしている。As described above, the intake system of the engine of the present invention provides a small space 8 between the bottom 51 of the seat 5 and the rear fender that integrally covers the lower part of the seat 5 and the upper part of the wheels 4, and furthermore, the small space 8 is provided at the periphery of the seat 5. A small gap 11 that communicates the small space 8 with the outside
Since the small space 8 is connected to the air intake port 21 of the air cleaner 2, air is sucked into the air cleaner 2 through the small gap 11 at the periphery of the seat 5 → the small space 8 → the connection port 9 → the air intake port 21. The rear fender 6 suppresses the upward movement of dust and water thrown up by the wheels while the vehicle is running, preventing dust and water from entering the small space 8 and preventing the air cleaner element, carburetor, and engine from being affected. That's what I do.

隙11のクリアランスは正確に保たれる。Further, the communication portion with the outside is provided by the seat 5 which is integrally formed with the upper beam ender 6 of the small space 8.
The small space 8 and the small gap 11 are formed by a part of the seat and rear fender, which are always installed in a vehicle such as a motorcycle. At the same time, the clearance of the small gap 11 is maintained accurately.
そして小空間8は、一体構成のシート5とリヤフェンダ
6の間に、シート5の底51を一部浮き上がらせるのみ
で簡単に設けることができる。The small space 8 can be easily provided between the seat 5 and the rear fender 6, which are integrally configured, by simply lifting a portion of the bottom 51 of the seat 5.
シート5と一体のりャフェンダ6を車体フレーム7に取

続の手間が省ける。When the fender 6 integrated with the seat 5 is attached to the vehicle body frame 7, the small space 8 and the intake port 21 of the air cleaner 2 are
Since it is connected by fitting into the elastic seal ring 10, the trouble of connection can be saved.

、シート性を向上する効果がある。In addition, since the shoulder of the air cleaner intake port 21 fitted into the lower end of the elastic seal ring 10 is in close contact with the inward lip 101 having an inverted cross section, it is protected against severe pitching and rolling of the vehicle body while driving. Even if the intake port 21 of the air cleaner
The connection point between the seal ring 10 and the elastic seal ring 10 does not shift, which has the effect of improving the sheeting properties.
