To provide a non-contact power supply device of a mobile body which can closely arrange a plurality of mobile bodies on a moving path and move them without complicating and enlarging the device.SOLUTION: A non-contact power supply device comprises an AC power source 4a for supplying AC power to each power supply coil, power supply coils 1A and 1B which are arranged so as to be isolated from each other and disposed being opposed to a mobile body 3 moving in the moving direction, and a drive unit 32 for generating voltage required to drive from output voltages of power reception coils. Power reception coils 2A and 2B are arranged so as to be isolated from each other in the moving direction. When the separation distance between the power supply coils is DT, and the separation distance between the power reception coils is set so that DT is larger than DR, voltage that is equal to or higher than a drive voltage is always generated on a drive voltage generation unit 32 by at least one of the output voltages of the two power reception coils.SELECTED DRAWING: Figure 1

    【課題】装置を複雑・大型化することなく、移動経路上に複数の移動体を密に配置して移動させることが可能な移動体の非接触給電装置を提供する。【解決手段】各給電コイルに交流電力を供給する交流電源4aと、互いに離間して配置され、移動方向に沿って移動する移動体3に対向配置された給電コイル1A、1Bと、受電コイルの出力電圧から駆動に必要な電圧を生成する駆動部32と、を備えた非接触給電装置において、受電コイル2A、2Bは、移動方向に沿って離間して2個配置されており、給電コイルの離間距離をDTとしたときに、受電コイルの離間距離DRが、DT>DRとなるように設定するとともに、二つの受電コイルの出力電圧の少なくとも一方によって駆動電圧以上の電圧が常に駆動電圧生成部32で生成される。【選択図】図1
