However, in the conventional structure described above, when the duct cover is opened and wiring is performed, all the duct covers must be removed, and at that time, the duct cover is accidentally dropped into the cable duct. There is a high possibility that caution is required during handling, and there is a problem that workability is poor.

Further, since the duct cover is placed on the top plate connecting bracket at the end of the top plate, when a large amount of wiring is performed between the cable ducts, the duct cover must be passed under the top plate connecting bracket. Therefore, wiring becomes very difficult. In addition, when storing large OA peripheral devices such as outlets and hubs, it is necessary to remove the duct covers on both sides.

On the other hand, when a desktop panel or the like is arranged at the center of the top plate, this panel is located on the duct cover. Therefore, when wiring processing is required, the panel must be removed each time wiring processing is required. In addition, if the duct cover is made large in consideration of the fact that wiring processing can be performed while the panel is mounted, there is a problem that the top plate surface becomes narrow accordingly.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and does not cause the duct cover to drop into the cable duct when the duct cover is opened and closed.

When the duct cover is unfolded flat, the front and rear engaging projections engage with the front and rear engaging recesses to close the cable duct and open any of the duct covers. The joint portion serves as a fulcrum and is opened in any direction in the front-rear direction.

Thus, when the duct cover is opened from either the front or the back of the top plate, the engaging projection on the opposite side rotates in the engaging recess to function as a fulcrum, and the duct cover can be opened.

When the duct cover is opened and folded in two as described above, the opening of the cable duct is substantially fully opened, so that the wiring work can be easily performed.

When the opposite duct cover is opened, the engaging projection on the opposite side rotates within the engaging recess and functions as a fulcrum. Similarly, if the duct is folded in two, the opening of the cable duct is opened. Fully open.

When it is necessary to remove the entire duct cover, it is possible to lift the duct cover directly upward from the closed state.
The engagement projection can be removed from the engagement recess and removed, and the opening of the cable duct can be fully opened.

The engaging projection is formed by bending an edge of the cable duct at a right angle, and the engaging recess is formed to have a substantially U-shaped cross section, and is formed between the top end of the upper piece and the top plate side. It is preferable that the engaging protrusions are inserted into the gaps of the first and second engaging portions so that the engaging protrusions engage with the lower surface of the upper piece and do not detach upward when the duct cover is erected. .

According to a third aspect of the present invention, if a locking portion is provided at the back of the engaging concave portion for fitting and locking the engaging projection of the open side duct cover, the duct cover can be opened. After being folded, the state can be maintained, and wiring processing can be performed more easily.

According to a fourth aspect of the present invention, a desktop panel is erected above the opening of the top plate along the longitudinal direction thereof, and does not interfere with the duct cover at the lower edge of the desktop panel when the duct cover is opened. By forming the cutout of the height, the duct cover can be opened and closed without any trouble even if the desktop panel is located above the opening, and wiring processing can be performed regardless of the presence of the desktop panel.
