Provided is a contactless power transfer device for a moving object, and in the contactless power transfer device, it can be simply determined whether a positional deviation between a power transmission coil and a power receiving coil is within an allowable range. Each of the power transmission coil and the power receiving coil comprises an H-shaped core, and search coils (Cy1a, Cy1b, Cy2a, Cy2b, Cx1, and Cx2) are installed on a magnetic pole object of the H-shaped core of the power transmission coil. A y-direction positional deviation between the power transmission coil and the power receiving coil is detected using voltages measured at Cy1a,Cy1b, Cy2a, and Cy2b, and an x-direction positional deviation is detected using voltages measured at Cx1 and Cx2. In addition, the directivity of positional deviation can be checked in the contactless power transfer device. |
