To prevent over heat of a part which generates heat as driving power transmission ratio increases in a driving power transmission.
Driving power of an engine 11 is transmitted to electromagnetic clutch mechanism 19. The driving power transmitted to a drive pinion 21 via the electromagnetic clutch 16 is transmitted to a left and a right rear wheel 24, 25 via a rear differential gear 20 and rear axles 22, 23. A temperature sensor 26 is attached on the rear differential gear 20. A electronic control unit 27 controls to energize the electromagnetic clutch mechanism 19 based on vehicle speed detection information obtained by a vehicle speed sensor 28, throttle opening information obtained by a throttle opening sensor 29, and temperature detection information obtained by the temperature sensor 26.
