The magnetic shield plate is arranged below all of the iron bolts.

Contactless power receiving device

It includes an electricity receiving coil unit having an electricity receiving coil that generates heats due to electrical conduction thererof, an electric component storage box having a rectifier, and a harness electrically connecting the electricity receiving coil unit and the electric component storage box with each other. Part of the harness is routed in a vicinity of a front end of an upper face of the electricity receiving coil unit. Flows are made turbulent when traveling air hits the harness, and thereby airflows behind the harness turn into turbulence. Even if affixes such as mud fixate on the upper face of the electricity receiving coil unit, the affixes are removed by the turbulence.
