Generally, when electrical equipment is provided on a slide body such as a slide seat of a vehicle, a power supply device is provided for supplying electric power from a power supply such as a battery mounted on the vehicle to an electric equipment. Such power supply device includes a wire harness for electrically connecting the power supply and the electrical equipment, and a case for accommodating the harness, and the wire harness is accommodated in the case or is drawn out from the case in response to a sliding movement of the slide body. At the end of such wire harness on the power source side end, a connector is provided, which fits in a mating connector connected to the power supply, which results in the power supply and the wire harness being electrically connected.
In order to connect the wire harness to the power supply in this manner, it is necessary to draw out a portion of the wire harness where the power source side connector is provided to the outside of the case. However, when conveying the electric device, the portion of the wire harness drawn out of the case becomes impeditive, resulting in a decrease in the workability of the conveying operation in some cases. So, there has been proposed a structure in which a wire harness is temporarily fixed to a case by clamping (see, for example, Patent Document 1). Using the wire harness temporary fixing structure described in Patent Document 1 makes the wire harness avoid becoming impeditive, and workability of carrying work improve.
