1. A power feeding device for a vehicle, comprising:

  • a high frequency power driver configured to convert electric power received from a power source into high frequency power that can achieve a magnetic field for transmission to the vehicle,a primary LC resonator configured to be magnetically coupled with a secondary LC resonator mounted on the vehicle by the magnetic field, and to transmit the high frequency power received from the high frequency power driver, the primary LC resonator including a transmission coil,a control device configured to adjust a frequency of the high frequency power by controlling the high frequency power driver such that the frequency of the high frequency power approaches a frequency of the primary LC resonator and a frequency of the secondary LC resonator, anda reflector formed at a rear side of the transmission coil with respect to a power transferring direction from the transmission coil, for allowing reflection of a magnetic flux output from the transmission coil in the power transferring direction,wherein the transmission coil and the reflector are arranged spaced apart from each other.
