きる。According to the skeleton structure of the wagon desk with the lifting top plate of the present invention, the main body mechanism part of the lifting mechanism for adjusting the height of the lifting top plate disposed above the skeleton and the supporting member 7 are provided. By incorporating it in both side plates of the body that is fully opened, the danger of finger jamming in the lifting mechanism part can be eliminated and the appearance can be improved, and the lifting mechanism further increases the weight and lengthens it. This is offset by using a lightweight side plate made of a plate material in which front and back surfaces of a core material that connects the plates vertically and horizontally are adhered to each other, and a vertical groove that is open upward to form a lifting mechanism is formed in the side plate. To reduce the strength of the skeleton due to this, while disposing the case of the main body mechanism section in the mounting opening and fixing the mounting plates provided on both sides of the case to both vertical reinforcing plates constituting the core material of the side plate, Left between main body mechanism parts on both sides Reinforced by connecting the tuning shaft of the lifting mechanism, the strength of the skeleton can be prevented from lowering. Further, since the lifting mechanism is provided inside the side plate, the inner size of the drawer can be set to the conventional size.
