PURPOSE:To increase the wind hole opening area and improve the cooling effect by forming wind holes for cooling wind on the cowling side faces covering the body of the engine both sides and wind holes for cooling wind also on the engine blankets suspending the engine side parts. CONSTITUTION:A radiator 5 is disposed between an engine 2 and a front wheel 3 in a motor-bicycle, and the both side face parts are covered with cowlings 6. The side parts of the engine are suspended by engine blankets 12 one ends of which are engagingly locked by the body frame, and wind holes 11 are provided adjacent to the engine blankets 12 on the both side faces of the cowlings 6. Further, wind holes 13 are also fromed in the engine blankets 12. The cooling wind passed through the radiator 5 from the front wheel side is passed through the wind holes 11 of the cowlings 6 and the wind holes 13 of the engine blankets 12 and exhausted. The increase in wind opening area enables an improvement in cooling effect. |
