An air duct 15 is formed by utilizing a box-shaped space surrounded by the folded portion 13 and the wall portion 14 and extending in the vertical direction. The air duct 15 is vertically formed along both side edges of the air guide port 10, and the upper end portion is closed by an extending portion 10a (see FIG. 1) extending from the upper part of the air guide port 10 toward the radiator 9 and the inlet 11 is closed. It communicates with the atmosphere in front of the vehicle body. The lower end of the air duct 15 is, as shown in FIG. 4, an outlet 17 that is bent and opened toward the center of the vehicle width.

きる。Next, the operation of this embodiment will be described. The traveling wind enters from the air guide port 10 to cool the radiator 9, and a part of it enters the air duct 15 from the inlet 11 and flows downward, and exits from the outlet 17 to bring the fresh relatively cool air to the funnel 8. Supply. At this time, since the outlets 17 are bent toward each other in the vehicle width center direction, the air flowing out from the outlets 17 does not directly blow on the funnel 8 and the influence of the wind pressure on the carburetor 7 can be mitigated.

There is no need to provide space in the vehicle width direction. In addition, since the folded-back portion 13 is closed by the wall portion 14, the side edge portion of the air guide port 10 is box-shaped and reinforced, and the rigidity of the cowling 1 as a whole is improved.
