PURPOSE: To provide a CVT suitable for a transmitter for a two-wheel drive type working vehicle without uselessness in a mechanism by setting a main shaft as an output shaft, and projecting both ends of the main shaft outward of a speed change case.
CONSTITUTION: A speed change unit 1 is such constituted that a plurality of driving rotating elements 7, which are revolvingly driven on an axis of a main shaft 3, are disposed around the main shaft 3 and a speed change member 10 capable of shifting in the axial direction is brought into contact with the driving rotating elements 7. An input rotating member 20 for driving the driving rotating elements 7 is fitted around the main shaft 3 for free relative rotation, where both ends of the main shaft 3 extend outward of a speed change case C for covering the speed change unit 1 and power take-off units 12, 12 for driving a traveling device are provided at both the extended ends of the main shaft 3, respectively, thus constituting a CVT. Consequently, since the input portion is disposed at one portion and a pair of output portions are located symmetrically to the speed change case, the CVT becomes suitable for a transmitter for a two-wheel drive type working vehicle requiring a couple of right and left driving wheel bodies.
