PURPOSE: To improve the cooling efficiency of a radiator by blocking a front face of a cowling covering a front part of a vehicle body by a guide face having a specific shape and arranging the radiator having a specific shape at the back of a window opened in an upper part of the guide face. CONSTITUTION: A cowling 8 covering a front part of a vehicle body is arranged from the back of a front wheel 1 to both sides of an engine 6. In this case, a front face of the cowling 8 is not opened and is blocked by a guide face 9 having an integral structure. The guide face 9 is formed on a face which has a shape in which a cross sectional face is bent into a recessed part and is inclined rearward and upward, and a window 10 is opened in an upper part thereof. Moreover, a radiator 7 is arranged just behind the window 10 and is formed into a shape of recessed and bent flat cross section in the same way. Consequently, running wind colliding on the whole guide face 9 is guided to the window 10 and is supplied to the radiator 7 to improve the cooling efficiency of the radiator 7. |
