Claims

[Scope of utility model registration request]

An internal combustion engine mounted on a body frame F of a motorcycle, comprising an engine body E consisting of a cylinder block 1 and a transmission case 2 connected below the cylinder block and having a crank chamber 3 and a mission chamber 4 inside. In the transmission case 2
A crankshaft 5 and an output shaft 9 are arranged side by side within the transmission case 2, and one side of the transmission case 2 has a drive pulley 10 provided on the crankshaft 5 and a driven pulley 11 provided on the output shaft 9. A continuously variable transmission T consisting of a belt 12 suspended between both pulleys 10 and 11 is provided, and a cooling air outlet is provided on the side wall of the transmission case 2, facing the back surface of the driven pulley 11. 45, the air guide passage 4 has an inlet 42 opened at the rear of the transmission case 2 at the air guide port 45;
A cooling device for an internal combustion engine for a motorcycle, comprising a suction fan 50 that communicates with the outlet 44 of the driven pulley 11 and sucks cooling air into the transmission case 2 from the air guide port 45 on the back side of the driven pulley 11.
