Document Type and Number:
Japanese Patent JP5253607
Kind Code:
B1
Abstract:
PROBLEM TO BE SOLVED: To provide a wireless power feeding device capable of easily increasing an allowable amount of positional deviation between a power feeding unit and a power receiving unit.SOLUTION: A wireless power feeding device includes: two primary coils 11 and 12; and a secondary coil 13 which is arranged so that the two primary coils 11 and 12 are interlinked with a magnetic flux 21 generated during energization of the two primary coils 11 and 12. The two primary coils 11 and 12 are arranged so that an angle θ formed by two planes S11 and S12 orthogonal to central axes A11 and A12 of the two primary coils 11 and 12 becomes 0 or more and less than 360 degrees.
