Abstract: A wireless power supply system includes: a primary power-supplying coil which is a power-supplying coil capable of wirelessly supplying electric power to another power-supplying coil; a first machine that supports the primary power-supplying coil; a secondary power-supplying coil which is a power-supplying coil wirelessly supplied with electric power from another power-supplying coil; and a second machine that can move while supporting the secondary power-supplying coil. The relative positional relationship or the relative attitudinal relationship between the first machine and the second machine can be adjusted corresponding to the movement or change in attitude of the second machine so that a state in which electric power is wirelessly supplied from the primary power-supplying coil to the secondary power-supplying coil is maintained.

Abstract: A movement mechanism includes a plurality of primary power-supplying coils each serving as a power-supplying coil that is able to supply power to another power-supplying coil in a wireless manner and arranged along an imaginary line parallel to the movement path, a secondary power-supplying coil serving as a power-supplying coil configured to receive power from another power-supplying coil in a wireless manner; and a movement structure serving as a structure configured to support the secondary power-supplying coil and to move along the movement path, wherein power is able to be supplied in a wireless manner to the secondary power-supplying coil from one or more of the primary power-supplying coils sequentially selected from among the plurality of primary power-supplying coils depending on an arrangement sequence when the movement structure moves along the movement path.
