[0024]

As described above, according to the present invention, a pair of left and right mounting members and a rod hung between them are provided in the mounting holes provided at the left and right positions of the desk top. Since the mounting rod is bridged between the mounting members by locking, it is possible to equip and use an individual desk top plate and an intermediate desk position between facing desk top plates, respectively. By changing the length, it is rational because it can be used for desks with different mounting hole intervals, and even if the heights of the desk tops facing each other are different, it is possible to equip them without any trouble. Further, according to the configuration of claim 4, since the operation hole can be closed by the shutter member when not in use, invasion of dust or foreign matter can be prevented and the appearance is good, and according to the configurations of claims 5 and 11, The parallelism of the mounting rod in the front-rear direction can be easily obtained, and according to the configuration of claim 6, the mounting members can be connected in the vertical direction, and the configuration of claims 7 and 10 is also provided. According to this, there is an advantage that the load acting on the mounting rod can be sufficiently resisted and the load resistance is excellent.
