Continuously variable transmission

A continuously variable transmission wherein a driving shaft coaxial with a crank shaft of an engine is rotatably supported by a transmission case, a driven shaft disposed in parallel with said driving shaft is rotatably supported by said transmission case, a driving pulley is mounted on said driving shaft, said driving pulley comprising a first driving pulley piece fixed onto said driving shaft and a second driving pulley piece mounted on the driving shaft in an axially movable and non-rotatable manner relative to the driving shaft, a driven pulley is mounted on said driven shaft, said driven pulley comprising a first driven pulley piece fixed onto said driven shaft and a second driven pulley piece mounted on the driven shaft in an axially movable and non-rotatable manner relative to the driven shaft, and a belt is entrained on both said driving pulley and said driven pulley, wherein a torque converter and a forward/reverse change-over mechanism are disposed on an input side of said driving shaft with respect to said driving pulley, an output clutch is disposed on an output side of said driven shaft with respect to said driven pulley, one side of a counter shaft is supported by said transmission case through a ball bearing, and an opposite side of the counter shaft confronts said second driven pulley piece and is supported by the transmission case through a roller bearing.
