必要がある。Prior art and its problems In small vehicles whose front part is covered with a body cover, the engine, carburetor, air purifier, etc. are placed in a place where they are shielded from the wind by the body cover. The temperature of the carburetor and air cleaner tends to rise due to the influence of heat, and this tendency is particularly exacerbated in the case of a V-type engine in which the carburetor is disposed in a space between cylinders arranged in a V-shape. When the temperature of the carburetor and air purifier increases, not only does the amount of intake air in the engine decrease, but the air-fuel ratio changes and the engine output decreases. It is necessary to suppress the rise in temperature of the vessel.

却効果を高めることができる。 The present embodiment is configured as described above, and when the motorcycle 10 is traveling, the traveling wind A enters into the wind guide tube 38 from the air intake port 36 of the vehicle body cover 34.
From the louver 44, the main pipe 14 on the left and right, the down tube 16, and the fuel tank 32 above the reinforcing member 24.
You will be guided into a space surrounded by and directional wall 54
The traveling wind B that changes the flow direction and blows out from the louver 44 is sent to the carburetor 26 and the air purifier 2.
8, cylinder C 1 of engine E,
The temperature rise in the vaporizer 26 is effectively suppressed by wiping away the hot air radiated from C 2 . Since the carburetor and the air purifier 28 are arranged one above the other in the space, the traveling air introduced into the space directly hits both and cools them well. In addition, the wind guide tube 3
8 is bent inward at the rear and communicates with the space from the side, so the left and right wind guide tubes 38 are extended to both ends of the head pipe 12 within the vehicle body cover 34 to ensure a large passage cross-sectional area. Therefore, a large amount of running air can be guided into the space to enhance the cooling effect.

気口が走行風Ｂの流れ方向に対して側方に位置し
ており、走行風Ｂの風圧の影響を直接受けること
なく、空気清浄器２８内に冷気が吸入される。 In addition, the intake pipe 30 of the air purifier 28 has its intake port located on the side with respect to the flow direction of the traveling wind B, so that the air purifier 28 is not directly affected by the wind pressure of the traveling wind B. Cold air is sucked inside.
