Abstract

A power reception device includes a power reception coil and a magnetic member. The power reception coil is arranged on a bottom surface of a vehicle main body. The power reception coil is configured to receive power tirelessly from a power transfer coil in a state of facing the power transfer coil. The power reception coil is provided to surround a winding axis that extends in a first direction crossing a direction to face the power transfer coil. The magnetic member is arranged on the bottom surface of the vehicle main body. The magnetic member has a shape that extends in the first direction. The magnetic member is arranged adjacent to the power reception coil in a second direction crossing the first direction.
