Abstract
A power receiving coil (22) is installed at a front portion on a lower surface of a floor panel (40) close to steered front wheels (W) and elongated across a lower open portion of a tunnel portion (42) located in the center of a vehicle (1). Therefore, the power receiving coil (22) can be accurately aligned with a power transmission coil (12) on the load surface side to face each other with a sense of steering in such a manner as to align the center of the vehicle with the power transmission coil (12) when the vehicle (1) advances to a predetermined stop position in a parking space (2).
