PURPOSE:To perform an effective cooling of the engine by travelling air by a provision of a radiator in a travelling air passage arranged under the engine. CONSTITUTION:The engine 7 is supported by a body frame 2 and the radiator 12 is mounted on the body frame 2 under the engine 7 by means of a pair of stays 18 and 19. The passage 11 is formed in a fairing 10 for leading the travelling air therethrough to the radiator 12. In comparison with the structure that the radiator 12 is arranged above the engine 7, the going around the engine 7 of the tranvelling air can be reduced at the time of the autobicycle running at a high speed, and therefore, a large amount of travelling air can be led to the radiator 12 effectively. |
