Claims

[Claims for Utility Model Registration] A continuously variable transmission comprising a variable diameter drive pulley, a driven pulley, and a V-belt suspended between these pulleys; a cover covering the continuously variable transmission;
A cooling structure for a belt-driven continuously variable transmission having outside air suction means into the cover, the axial flow fan rotatable in contact with the V-belt between both pulleys, and the shaft of the cover. A cooling structure for a belt-driven continuously variable transmission, characterized by having a flow fan and an exhaust port that opens at a position adjacent to the flow fan.
