Inductive power supply system for electric operation machine

An object of the present invention is to provide an inductive power supply system for an electric operation machine capable of readily increasing an allowable amount of a positional displacement between primary and secondary coils. [0002] An inductive power supply system for an electric operation machine having an electric storage device and a power receiver 41 includes a power feeder 51 provided with a pair of primary coils 11 and 12 connected in series circuit to generate a magnetic dipole at energization. The power receiver 41 has a secondary coil 13 interlinkable to a magnetic flux generated by the primary coils 11 and 12 at the energization of the primary coils 11 and 12.
