PROBLEM TO BE SOLVED: To provide a structure with a simple structure suitable as a specific vehicle such as an agricultural tractor and a bulldozer, capable of constituted to compact size and light weight and having excellent transmission efficiency. SOLUTION: Motive power of an engine 9 is transmitted to a pair of output shafts 12a, 12b through one input shaft 11 and a pair of continuously variable transmissions 13a, 13b provided on both ends of the input shaft 11. These continuously variable transmissions 13a, 13b are formed by assembling troidal type continuously variable transmission units 15a, 15b and planetary gear type transmission units 16a, 16b between the input shaft 11 and both output shafts 12a, 12b. Further, it is provided with function that the rotation state of the output shafts 12a, 12b is rotated in both directions while clamping the stopping state in the state that the input shaft 11 is rotated in a predetermined direction based on adjustment of a transmission ratio of the troidal type continuously variable transmission units 15a, 15b of them.
