However, in such a structure, since the wiring box is fixed to the back plate, it is difficult to reach the openings on the upper surface and the front surface, and the wiring box is opened through the openings. It often happens that the work of putting the cable in and out is difficult.

Since the lower edge of the side opening is located higher than the receiving surface for receiving the cable in the wiring box,
When the cable is led out from the wiring box through the opening on the side surface, problems such as an outlet or a connector larger than the cable being caught in the step between the opening and the receiving surface are likely to occur. Further, in such a structure, by sequentially pushing the cables into the wiring box, the tip of the cable cannot enter the wiring box of the adjacent desk through the side opening. Therefore, it is not possible to smoothly carry out the wiring work in the lateral direction when the cables are inserted from one wiring box to the adjacent wiring box through the openings on the side surfaces with the desks adjacent to each other.

Further, in such a structure, since the cable standing up from the floor is exposed in the lower limb space below the top plate, it is unsightly, and there is a possibility that the cable may get caught on the cable and the wiring may come off.

An object of the present invention is to eliminate all such problems.
