Power receiving device, power transmitting device, and power transfer system
First Claim
1. A power receiving device comprising:
- a power receiving unit receiving electric power from an external power transmitting unit contactlessly;
a first coil provided in said power receiving unit;
a first shielding wall surrounding said first coil and defining a region in which an electromagnetic field formed around said first coil is radiated;
a first device accommodated inside said first shielding wall;
a first shielding casing having said first device accommodated therein, said first shielding casing being also disposed inside said first shielding wall; and
a first wiring connected to said first device and extending from inside said first shielding casing to outside said first shielding casing, and also pulled outside said first shielding wall,said first shielding casing having an external surface including a first opposite portion closer to said first shielding wall than said first coil,said first shielding wall having a first region opposite to said first opposite portion, said first region having a first hole,said first wiring being pulled outside said first shielding wall through said first hole.
