本発明は自動二輪車等に搭載されるエンジンのエアクリ
ーナに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air cleaner for an engine mounted on a motorcycle or the like.
一般にエンジンに備えられるエアクリーナにおいては、
空気中の塵埃を捕捉するイケ用のほか、シリンダに空気
が吸込まれる際に発生する吸気騒音を低減する作用も重
要である。そのため、従来、吸気ダクトを細長く形成し
、この吸気ダクトの基端部をエアクリーナのケースに取
付けることにより、エンジンの吸気管とエアクリーナの
ケースとで得られる消音効果をさらに効果的なものにし
ている。In air cleaners that are generally installed in engines,
In addition to capturing dust in the air, it is also important to reduce the intake noise that occurs when air is sucked into the cylinder. Therefore, conventionally, the intake duct is formed into a long and narrow shape, and the proximal end of the intake duct is attached to the air cleaner case, thereby making the noise reduction effect obtained by the engine intake pipe and the air cleaner case even more effective. .
しかし、従来のこの種エアクリーナにおいては、細長い
吸気ダクトを基端部で保持する構造であるため、自動二
輪車等の走行に伴う振動・衝撃等により吸気ダクトに振
らつきが生し問題となっている。すなわち、振らつきに

クトがケース等と共鳴し振らつきが激しくなる場合にお
いて著しい。However, since conventional air cleaners of this type have a structure in which the elongated intake duct is held at the base end, vibrations and shocks caused by motorcycles, etc., cause the intake duct to wobble, which poses a problem. . That is, the air intake duct is deformed due to the swinging and stress is concentrated at the base end, making this part more likely to be damaged. Furthermore, since the shape of the intake duct changes, the air intake resistance changes, which affects the amount of air taken in. This effect is particularly significant when the intake duct resonates with the case and the like, causing severe shaking.
本発明はこのような事情に鑑みなされたもので、吸気ダ

する保持部材を設けものである。The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an air cleaner that can prevent damage to the intake duct and reduce the effect that the intake duct has on the amount of intake air. In the air cleaner according to the present invention, an insertion hole is formed in the case, and when the intake duct is held at the inner peripheral edge of the insertion hole, a holding member is provided in the case to hold the outer peripheral edge of the proximal end of the intake duct. be.
本発明においては、吸気ダクトを基端部および略中央部

をはかることができる。Therefore, the intake duct 20 can be held in two positions and movement at these holding parts can be prevented, so that swinging of the intake duct can be reduced. In other words, the intake duct 1-20 is attached to the case 12 with the holding member 21, and is attached to the insertion hole 1 of the lower case 1.2C.
At 9, shaking is suppressed. As a result, the amount of deformation of the intake duct 20 can be reduced, and changes in air intake resistance can be suppressed. Furthermore, since a portion of the intake duct 20 is housed within the case 12, the volume of the inlet side chamber 15 can be increased without increasing the size of the air cleaner 11.
