2. Description of the Related Art In a conventional steel desk, a structure for mounting a top plate on a sleeve portion is disclosed in Japanese Utility Model Publication No. 58-46674. In the mounting structure described in this publication, an engagement groove is formed in a side surface portion of a rear reinforcing member of a top plate, an engaging hole serving as a dharma hole is formed in a front reinforcing member, and a rearward engaging member is formed on a rear crosspiece of a sleeve portion. At the same time as forming a dovetail, a headed engaging projection is fixed to the front beam, and at the rear, the engaging claw is locked in the engaging groove at the rear while sliding the top plate forward with respect to the sleeve. At the front part, the engagement protrusion is engaged with the engagement hole, and at this time, the front surface of the protrusion of the detent member elastically urged upward to the front rail of the sleeve portion contacts the rear surface of the front reinforcement member of the top plate. Thus, the engagement between the sleeve and the top plate is maintained.

[0003] In the work of connecting the sleeve and the top plate,
All positions of the engaging groove and the engaging claw, and the engaging hole and the engaging protrusion must be simultaneously and accurately determined with the top plate being substantially horizontal with respect to the upper surface of the sleeve portion. There was such a problem. In addition, since the engaging claws, the engaging protrusions, and the protrusions of the detent members protrude from the upper surface of the sleeve portion, there is a risk that these protrusions may be deformed or damaged when the sleeve portion is packed or transported. In addition, although there is an advantage that a tool is not necessary in the assembling process, three types of engaging members or processing such as an engaging groove and an engaging claw, an engaging hole and an engaging protrusion, and a detent member are required. Must also be formed with high precision, so that it does not contribute much to cost reduction.

In the case of separating the sleeve and the top plate,
With the drawer of the sleeve removed, the top must be slid rearward while inserting the hand inside the sleeve and pushing in the protrusion of the detent member that protrudes into the inside of the top. Not only was the work cumbersome, but there was also the risk of pinching fingers.

[0005]

SUMMARY OF THE INVENTION In view of the above situation, the present invention seeks to solve the problem before the assembling operation.
There is no protrusion on the upper end surface of the sleeve or leg and the lower surface of the top plate, and the top plate can be easily and firmly attached to the upper end surface of the sleeve or leg with one touch. Another object of the present invention is to provide a desk top plate mounting structure that does not require removal of a drawer when the sleeve and the top plate are separated from each other by simplifying the structure by making the mounting structure common to the parts.

[0006]
