Abstract:
An object is to provide a moving object structure capable of reducing power loss caused when power is supplied from a power feeding device to a moving object by wireless communication. Another object is to provide a moving object structure capable of reducing the strength of a radio wave radiated to the surroundings. Before power is supplied to a moving object, a radio wave for alignment of antennas is output from a power feeding device. That is, radio waves are output from a power feeding device in two stages. In a first stage, a radio wave is output to align positions of antennas of the power feeding device and the moving object. In a second stage, a radio wave is output to supply power from the power feeding device to the moving object.
