In belt-driven power transmission systems, variable-pitch pulleys are mounted on both the drive shaft and the driven shaft. By forcibly changing the pitch on the drive side and causing the driven side to follow suit, the transmission ratio can be adjusted without changing the distance between the drive and driven shafts. This unit incorporates an ANS model as the transmission mechanism and is configured so that the output shaft of the reduction gear can be routed vertically.
