NONCONTACT ELECTRIC POWER RECEIVING DEVICE, NONCONTACT ELECTRIC POWER TRANSMITTING DEVICE, NONCONTACT ELECTRIC POWER FEEDING SYSTEM, AND ELECTRICALLY POWERED VEHICLE
First Claim
1. A noncontact electric power transmitting device for an electrically powered vehicle comprising:
- an electric power transmitting resonator for receiving electric power from a power source to generate an electromagnetic field, and transmitting the electric power to an electric power receiving resonator by resonating with said electric power receiving resonator through said electromagnetic field; and
an electromagnetism shielding material provided to surround said electric power transmitting resonator and having an opening at one side thereof to allow said electric power transmitting resonator to transmit the electric power to said electric power receiving resonator.

Abstract
A first shielding box is disposed so that its first surface can be opposite to an electric power feeding unit. The first surface has an opening and remaining five surfaces thereof reflect, during reception of electric power from the electric power feeding unit, a resonant electromagnetic field (near field) generated in the surroundings of the electric power receiving unit. The electric power receiving unit is provided in the first shielding box to receive the electric power from the electric power feeding unit via the opening (first surface) of the first shielding box. A second shielding box has a similar configuration, i.e., has a second surface with an opening and remaining five surfaces thereof reflect the resonant electromagnetic field (near field) generated in the surroundings of the electric power feeding unit.
