As a conventional desk for OA equipment, there is known a desk in which a wiring processing duct is built in the desk body so that a certain amount of wiring cables can be stored.

[0004]

In a conventional desk for OA equipment, since the outlet for drawing the wiring cable out of the duct is generally small, when the feed wiring is performed toward the adjacent desk, the desk is not connected. There is a problem that the wiring cable is bent and cannot be wired through the shortest distance, and a large amount of the wiring cable cannot be fed and wired.

Therefore, when a large amount of wiring cables need to be fed and wired, for example, Japanese Laid-Open Patent Publication No. 2-178.
It is uneconomical to install a large-scale system desk having a structure different from that of an ordinary desk, as described in Japanese Patent Publication No. 06-06, in exchange for an existing desk.

Further, as described in Japanese Utility Model Laid-Open No. 1-152529, there is also an existing desk in which floor-standing type wiring boxes are arranged in parallel so as to accommodate a large amount of wiring cables. However, since this wiring box is installed adjacent to the desk independently of the desk body, it is inevitably configured in the shape of a box, and also when feeding between adjacent wiring boxes, A wiring cable cannot be passed in the shortest distance, and a large amount of feed wiring is impossible.

The present invention solves these problems and makes it possible to increase the amount of wiring cables accommodated and the amount of feed wiring without using any modification to an existing desk. An object is to provide a wiring duct device.

[0008]

In order to achieve the above-mentioned object, the present invention secures a wiring receiving gutter having a side open to the rear surface of a vertical substrate and fixes the upper end of the vertical substrate. By engaging the engagement hooks in the duct main body, which is bent forward to form the engagement hooks, with the upper edges of the curtain plates on the rear surfaces of the pair of front and rear desks, the duct main body is locked. , And a common side cover is detachably attached across the duct main body facing the front and rear.
