部固定装置が提供されている。2. Description of the Related Art There have been provided various height adjustment devices for a tabletop in a conventional learning desk. For example, as disclosed in Japanese Utility Model Publication No. 39649/1993 filed by the applicant of the present invention, the height adjustment device is provided in a vertical direction. Top plate elevating means comprising a leg provided with stop holes at regular intervals and a leg insertion portion for elastically inserting the leg, and a receiving surface on one side of the base, the receiving surface having a tapered shape. The wedge portion is disposed closer to one side of the receiving surface, and a shaft body protrudingly provided on a side surface of the base in a direction perpendicular to the wedge portion so as to be inserted into a stopper hole provided in a leg of the top plate elevating means. There is provided a top plate fixing device for a desk which is adjustable in height of a top plate, comprising a receiving member and a position fixing member for fixing the position of the leg play insertion portion and the leg at the stopper hole of the leg.

る。In the above-mentioned apparatus, first, the shaft of the temporary receiving member is inserted into the stopper hole of the leg of the top plate elevating means, the temporary receiving member is positioned on the side of the leg, and the wedge portion is connected between the leg and the leg insertion portion. After inserting it into the gap and engaging it with the step of the opening edge of the leg play insertion portion on the receiving surface and temporarily receiving it, it is fixed with the position fixing member, so it is necessary to fix the leg to the desk main body. It requires two members, a temporary receiving member and a position fixing member, especially when the stopper holes are formed in two rows along both side edges of the legs, a pair of the position fixing members are necessary according to the stopper holes, There is a disadvantage that a total of three members are required and the number of parts is large. Furthermore, since the wedge portion of the temporary receiving device is inserted between the outer surface plate of the leg insertion portion and the leg, the load of the top plate portion is supported by the wedge portion in the temporary receiving state, and the surface plate is moved outward. There is also the problem of swelling.

A structure in which the overlapping portion of the leg and the side plate is fixed with a pair of screws at two positions is provided, but the leg and the side plate are overlapped inside and outside, and further for attaching a temporary receiving device. Since the two rows of holes and the two rows of holes for screwing are exposed on the side surfaces, the appearance is inferior.
