NOVELTY - The vehicle has a power-supplying generator (33) driven by an engine (31) and including a rotating shaft (331) misaligned from a crankshaft (311). A vehicle power generating apparatus (2) comprises a clutch unit including a clutch (21) placed on the crankshaft, a driving gear (23) placed on the clutch, and a switching mechanism (24) driving the clutch. A motion transmitting unit (25) includes a driven gear (26) meshing with the driving gear and an input shaft (27) driven by the driven gear and co-rotatable with the rotating shaft. A shaft coupler (28) interconnects the shafts.    USE - Vehicle for camping purpose.    ADVANTAGE - The rotating shaft is misaligned from the crankshaft of the engine, so that the width of the vehicle is reduced effectively, and the structural strength of the rotating shaft and the crankshaft is increased. The vehicle controls the engine to run idly, so that the crankshaft is maintained at the preset rotational speed to rotate the rotating shaft smoothly to generate sufficient electric energy from the power-supplying generator and reduce consumption of fuel. The vehicle allows rotational speed of the input shaft to be changed by adjusting tooth number ratio of the driving gear and the driven gear to conform to a different type of the power-supplying generator. The vehicle allows an actuator to allow power to be transmitted from the crankshaft to the power-supplying generator, so that controllability of the vehicle power generating apparatus is high. The input shaft is connected to the rotating shaft by the shaft coupler so as to smooth rotation of the input shaft and the rotating shaft. The vehicle allows a clearance between the input shaft and the sleeve to be eliminated due to presence the biasing spring so as to reduce noise generated during rotation of the input shaft and the rotating shaft.
