Dry CVT(Continuously variable transmission) consists of a driving pulley and a driven pulley joined by rubber V-belt. Each pulley consists of a fixed flange and a movable flange. The movable flange of the driving pulley has centrifugal rollers and a ramp plate in it. The movable flange moves toward a fixed flange under the actuation of a centrifugal roller, as the driving pulley speed increases. In this study, computer simulation for a driving pulley was carried out for the purpose of analysis a Dry CVT. Based on the simulation we investigated relations between each omponent of driving pulley that consists of roller, movable flange and ramp plate
