Noncontact electric power receiving device, noncontact electric power transmitting device, noncontact electric power feeding system, and vehicle

A noncontact electric power transmitting device transmitting electric power from a power source to an electric power receiving device via an electromagnetic field generated by electromagnetic resonance with said electric power receiving device, comprising:

• an electric power transmitting unit transmitting said electric power to said electric power receiving device by electromagnetic resonance;
• a case housing said electric power transmitting unit therein;
• and
• electrical equipment installed within said case,
• said electrical equipment including
• an electric power receiving antenna receiving electric power from said electromagnetic field, and
• an electric load using the electric power received by said electric power receiving antenna.

A vehicle, comprising:

• a noncontact electric power receiving device receiving electric power from a power source external to said vehicle via an electromagnetic field generated by electromagnetic resonance with an electric power transmitting device external to said vehicle, and
• an electrical drive apparatus receiving the electric power received by said noncontact electric power receiving device to generate driving force for traveling said vehicle,
• said noncontact electric power receiving device including
• an electric power receiving unit receiving electric power transmitted from said electric power transmitting device, by electromagnetic resonance,
• a case housing said electric power receiving unit therein, and
• electrical equipment installed within said case,
• said electrical equipment including
• an electric power receiving antenna receiving electric power from said electromagnetic field, and
• an electric load using the electric power received by said electric power receiving antenna.
