が知られている。Motorcycles have an engine mounted in the front lower part of the frame.
The carburetor is placed behind the cylinder, which is tilted slightly forward, and the air cleaner is placed behind the carburetor. Then, a vaporizer mixes fuel into the intake air from which dust has been removed using an air cleaner to form intake gas, which is sucked into the engine's intake holes. Therefore, the air cleaner is located below the seat at the upper center of the frame. The cushion unit for the rear hawk is attached to the center of the frame, and there are space constraints, such as the small volume of the cleaner box and the need to make a recess in a part of the cleaner box. receive. Incidentally, as an air cleaner in which the filters are stacked in two layers, Utility Model Application Publication No. 14271/1984 is known.
エアークリーナーのクリーナーボックスの容積が制約を
受けて小さくなったり、クリーナーボックスが変形した
ものになると、内側に挿入するエレメントの大きさが小
さくなり、濾過面積が少なくなって吸気抵抗が増し、エ
ンジンの吸気効率が低下する不都合がある。If the volume of the air cleaner box becomes smaller due to constraints, or if the cleaner box becomes deformed, the size of the element inserted inside will become smaller, reducing the filtration area and increasing intake resistance, which will reduce the engine speed. There is a disadvantage that the intake efficiency decreases.

したことにある。In order to achieve the above object, the air cleaner for a motorcycle of the present invention connects a small diameter filter to the rear side under a large diameter filter and communicates the inside with a communication hole. Attach the inlet tube by inserting it inside the top plate of the filter.To install the top of the cleaner box, fit the top plate of the large diameter filter into the hole and tighten it.Connect the outlet tube to the front top of the cleaner box. This is because a recess is provided at the lower front of the cleaner box.

、後ホークのクツションユニットの上部が位置できる。A large-diameter feeder and a small-diameter filter can be stacked one on top of the other and inserted into a deformed cleaner box with a recess in the front lower part, ensuring sufficient filtration area and improving intake efficiency with less intake resistance. It makes a good air cleaner. The large-diameter filter and the small-diameter filter are stacked one on top of the other and their insides communicate with each other through a communication hole, so a long inlet tube can be inserted and suction noise can be reduced. Furthermore, the upper part of the rear fork cushion unit can be placed in the recess at the front lower part of the cleaner box.
