A transfer device transfers an electric vehicle, that has been loaded onto a pallet, in a left-right direction or in an up-down direction relative to the direction of forward travel of the electric vehicle. The pallet is provided with: a power-receiving coil that, together with a power-supplying coil of the electric vehicle, forms an electromagnetic coupling circuit; a power-receiving circuit that receives power that is supplied wirelessly from the outside via the electromagnetic coupling circuit; and an electric motor that is driven by power received by the power-receiving circuit, and that causes the pallet to move in the left-right direction or in the up-down direction.
