Abstract

PURPOSE:To improve performance of cooling an engine by introducing travelling wind blowing from above to below along a front fender toward the engine by cooling fins extending forward. CONSTITUTION:Fins 18a of cooling fins 18 located near and at the underside of a blow-by hole 20 are provided at the front portion to extend forward farther than the other fans 18. Thus, the fins 18a receive wind directed from above to below and deflect the wind to the front face of a cylinder body 13 so that travelling wind can be securely applied to the cylinder body 13. Further, a great amount of the travelling wind flows through the respective blow-by holes 20 so that performance of cooling the cylinder body 13 can be improved.
