The CVT includes a rotatable drive clutch connected to an input shaft (the input shaft being connectable to an engine), and a roller clutch carried on the input shaft. The CVT also includes a rotatable driven clutch connected to an output shaft, the driven clutch having a laterally stationary sheave and a laterally movable sheave that is normally biased toward the stationary sheave. An endless flexible drive belt is disposed about the drive and driven clutches.
