Abstract
A motorcycle having an engine with a built-in dynamo therein is provided with a second dynamo in addition to the first dynamo. This second dynamo is used for purposes other than that for the driving of a vehicle. This second dynamo is installed outside of the engine and driven by the engine through a belt transmission device. Provision is made to establish a driving relation between the second dynamo and the engine, or to disconnect such relation. The belt transmission device is covered with a cover having an air inlet port, a cooling fan is mounted on a rotor shaft of the second dynamo, and the belt transmission device is compulsorily cooled by air flowing from the air inlet port to the second dynamo. A socket for taking off the output of the second dynamo is provided on the vehicle body. The motorcycle includes a vehicle body having a main frame and a lower frame extending in a generally parallel relation with respect to each other. The engine is supported on the lower frame. The second dynamo is positioned in a space above this engine and under the main frame.
