PROBLEM TO BE SOLVED: To provide a power feeding system between road vehicles which can improve the transmission efficiency of energy, and can alleviate a load of a power receiving device caused by excessive power transmission. SOLUTION: The power feeding system between the road vehicles comprises the power receiving device 20 which is mounted to the vehicle 50, and receives a microwave via a power receiving antenna 21, and a power transmission device 10 which is arranged at a road side, and transmits the microwave via a power transmission antenna 15. The system is also characterized in that a power transmission output of the power transmission device 10 is variable according a distance between the power receiving antenna 21 and the power transmission antenna 15, or according to the direction of the power transmission of the microwave which should be transmitted via the power transmission antenna 15.
