1. A power receiving device arranged on a bottom surface of a vehicle body, comprising:
- a power receiving coil formed to surround space around a coil central axis extending in a front-back direction of the vehicle body, for receiving electric power from a power transmitting coil in a non-contact manner while facing the power transmitting coil;
a capacitor arranged adjacent to the power receiving coil in the direction in which the coil central axis extends;
a shield arranged between the power receiving coil and the capacitor, the shield including;
a wall portion positioned between the power receiving coil and the capacitor, anda fixing portion for fixing the wall portion to a housing containing the power receiving coil; and
a fastening tool fixing the power receiving coil to the housing;
wherein a width dimension of the fixing portion in a width direction of the vehicle body is larger than a width dimension of the power receiving coil in the width direction of the vehicle body, and the fixing portion is fixed to the housing by the fastening tool.

Abstract
A power receiving device includes a power receiving coil formed to surround space around a coil central axis extending in a front-back direction of a vehicle body, for receiving electric power from a power transmitting coil in a non-contact manner while facing the power transmitting coil, a capacitor arranged adjacent to the power receiving coil in the direction in which the coil central axis extends, and a shield arranged between the power receiving coil and the capacitor. The effect on the capacitor during electric power transmission can be reduced.

3. A power receiving device arranged on a bottom surface of a vehicle body, comprising:
-
a power receiving coil formed to surround space around a coil central axis extending in a front-back direction of the vehicle body, for receiving electric power from a power transmitting coil in a non-contact manner while facing the power transmitting coil; a capacitor arranged adjacent to the power receiving coil in the direction in which the coil central axis extends; a shield arranged between the power receiving coil and the capacitor; and a core around which the power receiving coil is wound; wherein, in the direction in which the coil central axis extends, a length between the shield and the core is longer than a length between the shield and the capacitor. - View Dependent Claims (4, 5)
