The proposed cone type CVT(Continuously variable transmission) is consisted of drive pulley, belt,belt move equipment, tensioner, belt guide and driven pulley. In this study, the function and therelationship of all parts in the cone type CVT were investigated. The speed ratio of cone type CVT atcase in parallel and incline movement of belt was analyzed. Proposed cone type CVT can apply toelectrical vehicle, scooter and golf cart etc..
