Description
【発明の詳細な説明】 （産業上の利用分野） この発明は自動二輪車のエアクリーナー装置に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to an air cleaner device for a motorcycle.
（従来の技術）

の吸気を浄化するためのエアクリーナーが設けられる場
合がある（例えば特公昭５７−３８４５０号公報）。In the above configuration, an air cleaner for purifying the intake air of the engine may be provided in a space sandwiched between the fuel tank and the engine and formed within the frame of the vehicle body frame (for example, Japanese Patent Publication No. 57-38450 Public bulletin).
（発明が解決しようとする問題点）
ところで、エンジンの吸気騒音ギ低減させるためには上
記エアクリーナーの容量を増大させることが好ましい。(Problems to be Solved by the Invention) Incidentally, in order to reduce the intake noise of the engine, it is preferable to increase the capacity of the air cleaner.
しかし、上記構成のようにタンクとエンジンに上下から
挟まれ、また、車体フレームにより左右から挟まれて形
成された空間は狭いものであり、また、その空間形状も
複雑なものである。However, as in the above configuration, the space formed between the tank and the engine from above and below, and between the vehicle body frame from the left and right is narrow, and the shape of the space is also complex.
従って、上記構成のようにこの空間にエアクリーナーを
設ける場合、その容量を十分に採ることは困難である。Therefore, when an air cleaner is provided in this space as in the above configuration, it is difficult to provide a sufficient capacity.

て車両の安定性が低下するおそれもある。Furthermore, if the fuel tank is moved upward in order to increase the capacity of the air cleaner in this space, the external shape from the fuel tank to the seat may become discontinuous, which may impair the appearance. Furthermore, if the fuel link is moved upward as described above, there is a risk that the center of gravity of the vehicle body will move upward and the stability of the vehicle will decrease.

上させることを目的とする。(Objective of the Invention) This invention was made in view of the above-mentioned circumstances, and aims to reduce engine intake noise by increasing the capacity of the air cleaner while maintaining a good appearance of the vehicle body. Furthermore, the purpose is to lower the center of gravity of the vehicle body and improve vehicle stability.

This air cleaner 13 is connected to the intake section of the engine 9 via an intake pipe 14 and a carburetor 15. Although not shown, fuel is supplied from the fuel tank 11 to the carburetor 15 via an oil supply pipe.

Further, the cleaner case 13a of the air cleaner 13 is made of resin, and is formed in an inverted U-shape similarly to the fuel tank 11, and is formed along the rear surface of the fuel tank 11. Same as above cleaner case 1
An intake hole 17 is formed in the lower surface of the cleaner case 3a at the center in the vehicle width direction, and one end of the intake pipe 14 is connected to both lower ends of the cleaner case 13a.

的に低減させることができる。(Effects of the Invention) According to the present invention, the air cleaner is disposed between the fuel tank and the seat, and the outer surfaces of the fuel tank and the seat are generally relatively flat, and the air cleaner has a box-shaped structure. Therefore, it is easy to form the outer surface of this air cleaner so that the fuel tank and the seat are connected by a continuous surface. Therefore, even if the air cleaner is provided between the fuel tank and the seat, the appearance of the vehicle body can be maintained in good condition. In this case, since the fuel tank and seat are sufficiently large in width and vertical dimensions, the capacity of the air cleaner can be sufficiently large.
This air cleaner can effectively reduce engine intake noise.
また、燃料タンクとシートとの間にエアクリーナーを設
けたため、従来、エアクリーナーを設けていた空間に燃
料タンクを拡張させるなど重量物を配置することができ

上させることがｆきる。Additionally, since the air cleaner is provided between the fuel tank and the seat, heavy objects such as the fuel tank can be expanded into the space where an air cleaner was previously provided. Therefore, it is possible to lower the center of gravity of the vehicle body and improve the stability of the vehicle.
更に、後面の面積が比較的大きい燃料タンクの後方にエ
アクリーナーが配置されたため、走行中に車輪の掻き上
げた砂などの異物がエアクリーナーに達することは燃料

空気をエンジンに供給することもできる。Furthermore, since the air cleaner is placed behind the fuel tank, which has a relatively large rear surface area, the fuel tank effectively prevents foreign matter such as sand scraped up by the wheels from reaching the air cleaner while driving. , it can also supply cleaner air to the engine.
