<P>PROBLEM TO BE SOLVED: To provide a non-contact power feeding device which is strong against the positional displacement of a primary-side coil and a secondary-side coil, and can be reduced in size and weight. <P>SOLUTION: The non-contact power feeding device includes the primary-side coil 42 wound around a primary-side core 41, and the secondary-side coil wound around a secondary-side core. The primary-side core is composed of a plurality of cores 41 arranged on a first plane with intervals, the secondary-side core is composed of a plurality of cores arranged on a second plane with intervals, and the primary-side coil and the secondary-side coil are arranged so as to oppose each other. Lines of magnetic forces which fill gaps between the cores are output from the plurality of cores 41 wound by the coil 42, so that the primary-side core 41 and the secondary-side core act as expanded cores including the gaps between the cores in their dimensions. By this arrangement, the non-contact power feeding device becomes strong against the positional displacement, thereby the cores can be easily manufactured at low cost. <P>COPYRIGHT: (C)2010,JPO&INPIT |
