To enhance a ratio of a magnetic flux passing though an inner side of a power reception coil.SOLUTION: A power reception device 14 that is provided to a vehicle 5 and receives a power from a ground power feeding device 1, includes: a power reception coil 22 that includes an axis line extended to a ground surface with an angle; a first magnetic member 51 that includes a non-conductive performance and a conductive performance, arranged to the ground surface side against the power reception coil; and a second magnetic member 52 that includes the non-conductive performance and the conductive performance that are arranged onto the side opposite to the ground surface side against the power reception coil. The second magnetic member includes a transverse member 53 extended over the power reception coil to a width direction of the vehicle. When viewing the first and second magnetic members to an axial direction of the power reception coil, it is arranged so as to be overlapped in the inner side of the power reception coil.SELECTED DRAWING: Figure 2

    【課題】受電コイルの内側を通る磁束の割合を高める。【解決手段】車両5に設けられて地上給電装置1から受電する受電装置14は、地面に対して角度をもって延びる軸線を有する受電コイル22と、受電コイルに対して地面側に配置された非導電性及び磁性を有する第1磁性部材51と、受電コイルに対して地面側とは反対側に配置された非導電性及び磁性を有する第2磁性部材52と、を有する。第2磁性部材は、車両の幅方向に受電コイルを越えて延びる横部材53を有する。第1磁性部材と第2磁性部材とは、受電コイルの軸線方向に見たときに、受電コイルの内側で重なるように配置される。【選択図】図2
