良好である。As described above in detail, in the present invention, it is sufficient to provide one power supply line for each of the two parallel traveling paths provided in parallel, Since the length of the power supply line is approximately half that of the conventional one, the cost of the power supply line, the cost of the power supply line installation member such as the power supply line installation plate, and the installation work time are halved. And since the length of the power supply line is about half,
The resistance loss of the power supply line and the eddy current loss in the surrounding members are approximately halved, and as a result, the capacity of the high frequency power source can be reduced. Furthermore, since it is possible to supply power to two moving bodies in the cross-sectional space for one conventional contactless power supply system,
The system can be downsized, and the peripheral electric field strength can be reduced. When the pickup core has a C-shaped cross section, the efficiency of power feeding is good.
