More specifically, the power supply rail 4 has a substantially S shape in a side sectional view. The power supply rail 4 has a power supply opening 4a that opens upward and a power reception opening 4b that opens downward.

  5, 6 and 7, the power supply opening 4a receives a power receiving plug E1a provided at the tip of a power cable E1 extending from the electric device E, and passes through the power receiving plug E1a. Thus, power is supplied to the electric equipment E. A first power supply electrode 41a is provided on the inner peripheral surface of the power supply opening 4a, in other words, one of the front wall surface and the rear wall surface, and the second power supply electrode 41b is provided on the other. Specifically, the electrode member 41 that supports the power feeding electrodes 41a and 41b is inserted into the power feeding opening 4a. The electrode member 41 has a substantially U shape when viewed from the side, and is formed by forming a first power supply electrode 41a on one of the front wall portion and the rear wall surface and a second power supply electrode 41b on the other side. Parts of the electrode member 41 other than the power feeding electrodes 41a and 41b are made of an insulator, for example, a resin. The height direction position of the first power supply electrode 41a is different from the height direction position of the second power supply electrode 41b. The electrode member 41 and the power supply electrodes 41a and 41b are continuously extended in the longitudinal direction, that is, the width direction together with the power supply opening 4a. Therefore, the power receiving plug E1a of the electric device E can be inserted at any position in the longitudinal direction of the power supply opening 4a, and the number of the power receiving plugs E1a is not limited to a fixed number.

  To supplement the power receiving plug E1a, a pair of power receiving electrodes E1x and E1y electrically connected to the electric device E are provided.
