Abstract:
1. A running power transmission mechanism for a vehicle for transmitting drive power from a driving source to steering and non-steerinng wheels, which are respectively disposed closer to first and second sides of the vehicle in a fore and aft direction thereof, comprising: a main-transmission device having a steering-wheel drive output shaft for outputting to the steering wheels drive power, which is synchronized with drive power outputted to the non-steering wheels; steering-wheel speed change device for non-stepwisely changing the speed of drive power inputted via the steering-wheel drive output shaft and outputting the drive power to the steering wheels, in which said steering-wheel speed change device is switchable between a standard transmission state, which outputs power enabling the steering wheels to have an average peripheral speed substantially equal to an average peripheral speed of the non-steering wheels, and a higher speed transmission state, which outputs power enabling the steering wheels to have an average peripheral speed higher than an average peripheral speed of the non-steering wheels; said steering-wheel speed change device including:
