Abstract
A continuously variable transmission includes: (a) a drive pulley and a driven pulley in which the pulley width between a fixed disk and a movable disk may be varied in accordance with oil pressure, (b) a V-belt, which is wound around the drive pulley and driven pulley, and (c) a clutch for controlling the transmission of torque from an engine to the drive pulley. The continuously variable transmission further has a first spring for constantly urging the movable disk of the drive pulley to the fixed disk side and a second spring for constantly urging the movable disk of the driven pulley to the fixed disk side.
