Abstract: A wire harness includes a cable constituted of a plurality of electric wires bundled together so as to include a plurality of cable ends and a plurality of connectors mounted one-to-one on the plurality of cable ends, wherein each of the plurality of connectors includes a connector terminal connected to an end of the electric wire, a tubular housing body accommodating the connector terminal, and a flange formed to project from an outer circumferential surface of the housing body. On a fitting side for fitting with a mating connector, the flange has a rugged shape that differs between the plurality of connectors.

Abstract: A power supply device includes a moving unit that moves a power supply fitting body in an insertion-extraction direction, an up-down direction, and a lateral direction that is orthogonal to the insertion-extraction direction and the up-down direction, and a controller that controls the movement of the power supply fitting body by the moving unit. A position detection device moves in linkage with the movement of the power supply fitting body by the moving unit. A power reception fitting body includes first structures extending along the lateral direction and second structures related to a central position of the power reception fitting body in the lateral direction. The first structure and the second structure are formed protruding to one side of the up-down direction with respect to a ceiling surface. The distances between the second structures and the first structures in the insertion-extraction direction are set in advance.
