ABSTRACT:
A running power transmission mechanism includes a main-transmission device and a steering-wheel speed change device. The steering-wheel speed change device in turn includes a non-stepwise speed change unit and a planetary differential unit. Drive power from the main-transmission device is inputted into a first element of the planetary differential unit, and output of the non-stepwise speed change unit is inputted into a second element of the planetary differential unit, while steering-wheel drive power is taken off from a third element of the planetary differential unit. Also, the speed of the output of the non-stepwise speed change unit is changed according to the steering angle of the steering wheels.
