NON-CONTACT POWER FEED DEVICE AND NON-CONTACT POWER TRANSMISSION DEVICE

In a non-contact power transmission device according to the present invention, a non-contact power receiving device includes a changeover portion (8) for opening and closing the connection between a power receiving coil (2) and a load device (10) which is supplied with electric power from the power receiving coil, the power receiving coil (2) being adapted to output electric power by receiving a high-frequency magnetic field from an induction heating apparatus used as a feeding apparatus, wherein a power-reception-side control portion for controlling opening/closing operations of the changeover portion is adapted to control the opening/closing operations of the changeover portion, in order to adjust the electric power supplied to the load device from the power receiving coil.
