PURPOSE:To form ventilative ports also with perfect means of waterproof, by forming a hollowly stepped part opened rearward and sideward to the upper face rear part of a cowling and vertically providing intake air ducts communicating the inside and outside of the cowling onto said hollowly stepped part then coating the hollowly stepped part with a cover. CONSTITUTION:Air is sucked from ventilative ports 27, 28 formed to a cover 19, and the air flows into an engine room 9 from air intake ducts 15 formed to a hollowly stepped part 10 of a cowling 8. In this way, even if water is intruded with the intake air from the ports 27, 28, the water is never guided directly to air intake holes 11, and intrusion of the water into the engine room can be prevented. |
