PROBLEM TO BE SOLVED: To provide a wireless power supply system for a vehicle which can prevent a reduction in power transmission efficiency between power transmission and reception coils when a turning angle changes due to turning of a wheel in the case of applying an in-wheel motor to a turning wheel.SOLUTION: A wireless power supply system 1 for a vehicle includes: a power reception coil 11 which is provided on a motor 13 arranged inside a turning wheel 20 and receives power in a non-contact manner; and a power transmission coil 31 which is provided on a vehicle body 40 for supporting the turning wheel 20 and transmits power to the power reception coil 11 in a non-contact manner. A plurality of the power transmission coils 31 are provided on the vehicle body 40 facing the power reception coil 11 rotating with the turning wheel 20 and are arranged in a rotating direction of the turning wheel 20.SELECTED DRAWING: Figure 1
【課題】インホイールモータを転舵輪に適用した場合において、転舵により転舵角が変化したときの送受電コイル間の電力の伝送効率の低下を防止することができる車両用ワイヤレス給電システムを提供する。【解決手段】車両用ワイヤレス給電システム1は、転舵輪20の内部に配置されたモータ13に設けられ、非接触で電力を受電する受電コイル11と、転舵輪20を支持する車体40に設けられ、受電コイル11に非接触で電力を送電する送電コイル31とを備え、送電コイル31は、転舵輪20と共に回動する受電コイル11と対向する車体40に設けられ、転舵輪20の回動方向に沿って複数配置される。【選択図】図1
