To efficiently supply power by making a primary coil and a secondary coil face each other accurately with a simple structure.SOLUTION: In a vehicle power supply device 2, a roadbed unit 4 is embedded in the ground surface. In the roadbed unit 4, an upper stage part 13 provided with a top plate 8 and a lower stage part 14 are laminated. The upper stage part 13 comprises: a hollow primary coil movement area 12 which stores a primary coil 3 in a movable manner; and a compression member 16 on the periphery thereof. The lower stage part 14 comprises: a columnar body 23a for load support which supports the compression member 16; and a columnar body 23b for cooling which radiates the heat generated by the primary coil 3 into the ground. A car stop 25 provided on the top plate 8 and sensors 27a, 27b of a console unit 26 detect the positions of tires 7 of an electric vehicle 1 to calculate the position of the secondary coil 5 provided on the bottom part. With an instruction signal from the console unit 26, a carriage 20 of the primary coil 3 is driven and the primary coil 3 is moved to the position immediately under the secondary coil 5.SELECTED DRAWING: Figure 1

    【課題】簡単な構造で一次コイルと二次コイルを精度良く対向させて効率よく電力を充電させる。【解決手段】車両給電装置2は路盤ユニット4を地表面に埋設している。路盤ユニット4は天板8を設けた上段部13と下段部14を積層した。上段部13は、一次コイル3を移動可能に収納した中空の一次コイル移動エリア12と、その周囲の圧縮部材16と、を有する。下段部14には圧縮部材16を支持する荷重支持用円柱体23aと一次コイル3の発熱を地中に放熱する冷却用円柱体23bとを有する。天板8に設けた車止め25とコンソールユニット26のセンサー27a、27bで電気自動車1のタイヤ7の位置を検出し、底部に設けた二次コイル5の位置を演算する。コンソールユニット26からの指示信号により、一次コイル3の台車20を駆動し、一次コイル3を二次コイル5の真下に移動させる。【選択図】図1
