•  The stepless shift mechanism consists of the primary and secondary pulleys, and the belt which connects them.

•  The primary pulley piston operates by oil pressure to perform variable shifting across the width of the primary pulley.

•  Consisting of metal elements and a metal link, the drive force is transmitted to the secondary pulley from primary pulley by compression action of the element.

•  The secondary pulley piston operates by oil pressure to maintain pull on the belt, which rotates variably across the width of the secondary pulley, so that it does not slip.
