The width direction of the duct cover is supported over the entire length of the duct cover by an attachment portion integrally provided on the curtain plate or the like over the entire length of the top plate opening in the width direction.

[0003]

However, in the case where the mounting portion of the duct cover is provided integrally with the curtain plate or the like over the entire length of the top plate opening in the width direction, when the size of the opening is different, Alternatively, when a desk top plate is provided alongside the partitioning device, it is necessary to integrally provide a duct cover mounting portion for each member, which not only complicates the structure of the members such as the curtain plate and deteriorates the workability but also reduces the width direction. Dimensional accuracy over the entire length is required. In addition, when such a mounting portion is integrally provided on the curtain plate, the packing property of the member is poor because the mounting portion protrudes from the curtain plate.

In view of the above, the present invention provides a wiring duct cover mounting structure for covering a top opening of a wiring duct, which is easy to manufacture, has good workability, and has no problem of dimensional accuracy. An object of the present invention is to provide a mounting structure which is excellent in packing property and the like, and which can respond to desks of various sizes and desks having different structures.
