PROBLEM TO BE SOLVED: To shorten an interval between an engine and a radiator by preventing a fan blade of a motor fan from being affected by the heat of an exhaust pipe, simultaneouly to improve the layout around the engine, and to reduce the discomfort given to a rider by preventing the air current of the motor fan from being heated by the exhaust pipe. SOLUTION: This device comprises a thermal insulation plate 37 between a fan blade 29 of a motor fan 25 and an exhaust pipe extending from a front surface of the engine. Whereby the heat of the exhaust pipe toward the fan blade 29 is cut by the thermal insulation plate 37, the fan blade 29 is not damaged by the heat, and the restriction on the relative position of the motor fan 25 and the exhaust pipe is released, so that an interval between the engine and the radiator (front wheel) can be shortened, and the layout around the engine can be improved. The air current of the motor fan 25 is not directly contacted with the exhaust pipe by mounting the thermal insulation plate 37, an amount of hot air is reduced, and the discomfort to the rider can be reduced. |
