PURPOSE: To effectively utilize opposed air flow which causes deterioration of running performance of a motorcycle as a means for improving the running performance, conversely. CONSTITUTION: Opposed air flow generated through running is taken in from an air take-in port 3 formed on a proper position of a vehicle body 1. An impeller 5 mounted on a transmission shaft or the like is rotated by the air flow. This torque is transmitted as rotational driving force for wheels. For instance, the air take-in port 3 is opened to a front panel of a cowl. The air flow taken in from the port 3 is introduced to the impeller 5 through a flexible hose 6. A nozzle 10 is arranged on an end of the hose for injecting the air flow to the impeller 5. |
