PROBLEM TO BE SOLVED: To improve ventilation in a top cowling by opening an air exhaust hole on the upper rear surface of a top cowling, and opening an air intake hole on the front side surface. SOLUTION: A space part covered with an air duct cover 2c is partitioned into an air intake chamber and an air exhaust chamber to form an air duct in which air flows from the outside of a top cowling 2 through an air intake hole 76 of the air duct cover 2c, an air intake chamber, and an air intake port of an upper cowling 2a into the inside of a top cowling 2. Further, an air duct is constructed in such a manner that air flows from the inside of the top cowling 2 through an air discharge port of the upper cowling 2a, an air discharge chamber, and an air discharge hole 77 of the air duct cover 2c to the outside of the top cowling 2. Accordingly, by the action of wind from the front during traveling, air can be positively discharged from the air discharge hole 77 to the outside of the top cowling 2, so that ventilation in the top cowling can be improved. |
