摘要： In a power transmission system for transmitting electric power from the primary side power feeding coil to the secondary side power receiving coil without their mutual contact and using electromagnetic induction, the power coils on each of the primary and secondary sides include a pair of planar spiral coils which are shaped in the form of a figure 8 and connected differentially to power supply, and each of the spiral coils is D-shaped having a semicircular portion and a linear portion combined together, the two spiral coils having their linear portions laid one on the other to form a planar figure-8 coil. Plates of soft magnetic material 4 and 41 are disposed each on a side of the power coil on one of the primary and secondary sides which is opposite to the side that faces the power coil on the other of the primary and secondary sides.

摘要： A power transmitting device includes: a power transmitting unit being able to contactlessly transmit electric power to a power receiving unit of a power receiving device; and a guide unit changing a guide position of the power receiving device at power reception of the power receiving device on the basis of a type of the power receiving unit. The guide unit may when the types of the power receiving and transmitting units are the same, set a position of the power receiving unit, at which center positions of the power receiving and transmitting units coincide with each other, for the guide position, and, when the types of the power receiving and transmitting units are different, set a position of the power receiving unit, at which the center positions of the power receiving and transmitting units deviate from each other, for the guide position.
