1. A traveling body system comprising:
a frame track including at least one metal rail, an electrical insulator disposed on a travel surface of the at least one metal rail, and two conductors, the two conductors being provided to the electrical insulator and supplied with an AC voltage;
a traveling body disposed within the frame track and provided with a first wheel and a second wheel, so as to travel on the two conductors; and
a voltage supplier to supply an AC voltage to each of the two conductors, so that a first of the two conductors and the first wheel define a first capacitor and a second of the two conductors and the second wheel define a second capacitor; wherein
the traveling body includes a power receiver to receive AC power from the first capacitor and the second capacitor, and a travel drive motor to directly or indirectly receive power after the AC power received by the power receiver is rectified; and
the two conductors are parallel or substantially parallel to a gap in a width direction, and the AC power is differentially transmitted to the two conductors.
