To improve efficiency for transmitting a driving force of a driving source to a pair of continuously variable transmission mechanisms, and accuracy of a rotation difference of front wheels.
In this driving device 10 for a vehicle, a pair of continuously variable transmission mechanisms 12L, 12R are provided between a crank shaft 54 of an engine 52 and both sides of a vehicle width direction, and input shafts 14 of the continuously variable transmission mechanisms 12L, 12R are arranged coaxially with the crank shaft 54 of the engine 52. Also, input side pulleys 18 of a pair of the continuously variable transmission mechanisms 12L, 12R are directly set to the crank shaft 54. Accordingly, there is no need of a transmission mechanism (such as a gear) for converting a driving transmission shaft from the engine 52 to a pair of the continuously variable transmission mechanisms 12L, 12R, so as to improve efficiency for transmitting the driving force of the engine 52 to a pair of the continuously variable transmission mechanisms 12L, 12R and accuracy of a rotation difference of front wheels 60.
