To provide a contactless power supply system and a contactless power reception device capable of suppressing the decrease in power transmission efficiency.SOLUTION: A contactless power supply system A1 includes a power reception unit 20, and a contactless power supply device 1. The power reception unit 20 is provided to an electric moving body 3 that is movable using the power of a storage battery 320. The contactless power supply device 1 supplies the power to the storage battery 320 of the parked electric moving body 3 using a contactless power supply transformer TR1. The contactless power supply device 1 has a power transmission unit 10 of a contactless power supply transformer TR1. The power transmission unit 10 supplies the power to the power reception unit 20 in a non-contact manner in a state where the power transmission unit 10 and the power reception unit 20 face each other while the electric moving body 3 is parked. The power reception unit 20 is located on the extension line of the wheel axle 311 of the electric moving body 3.SELECTED DRAWING: Figure 1
【課題】電力の伝達効率の低下を抑制可能にすること。【解決手段】非接触給電システムA1は、受電部20と、非接触給電装置1と、を備える。受電部20は、蓄電池320の電力を用いて移動可能な電動移動体3に設けられる。非接触給電装置1は、駐車中の電動移動体3の蓄電池320に、非接触給電トランスTR1を用いて給電する。非接触給電装置1は、非接触給電トランスTR1の送電部10を有する。電動移動体3の駐車中に、送電部10と受電部20とが対向している状態で、送電部10が受電部20に非接触で給電している。受電部20が、電動移動体3が備える車輪の車軸311の延長線上に配置されている。【選択図】図1
