Background

A conventional scooter motorcycle generally has a Transmission case interposed between an engine and a rear wheel, and the Transmission case has a Continuously Variable automatic Transmission (Continuously Variable Transmission) therein for converting power generated by the engine into rear wheel driving force. Because the stepless automatic transmission generates high temperature when in operation, and the high temperature can reduce the power conversion efficiency and reduce the service life of parts, an air inlet hole is generally formed in the front of the transmission case, air enters the transmission case through the air inlet hole and is exhausted through an exhaust hole in the rear direction of the transmission case, and air circulation is formed to dissipate heat. However, the existing design of the air inlet is usually closer to the road surface, and then road surface pollutants (such as sand, dust, gravel, water and the like) enter the transmission case, so that the conversion efficiency of the stepless automatic transmission is reduced, and even the service life of the stepless automatic transmission is shortened.
