The scooter CVT is consisted of driving pulley, rubber V-belt and driven pulley. A driving pulley of
CVT plays a vital role. In this study, contact forces of movable flange, roller and ramp plate are analyzed for wear of roller. As the results, 1) when incline angle of ramp plate become decreased, reaction difference of ramp plate and movable flange become increased, so roller wear can be decreased, 2) when radius of movable flange profile is increased, reaction difference become increased also. Roller wear had been caused serious claim. Based on the analysis, advanced model of driving pulley is presented.
