When the through holes 81 formed in 11 coincide, the interruption shaft 84 is inserted into the interruption hole 82 of the rear platform. That is, the pressing plate 851 is rotated in the opposite direction to which the pressing plate 851 is rotated by the elastic force of the spring 852 compressed between the pressing plate 851 of the spring pressing means and the lower plate 21 of the spring pressing means by the lever 831 operation. The intermittent shafts 84 on both sides of the rotary shaft 83 are inserted into and fastened to the through holes 81 and the intermittent holes 82 so that the lifting positions of the rear platforms are interrupted.

On the other hand, when the user forcibly presses the rear of the desk top plate 5 while the top plate of the desk is inclined at a predetermined angle as described above, the intermittent shaft 84 inserted into the intermittent hole 82 through the through hole 81. The rear lifting platform 7 is lowered to the inside of both vertical pipes 11 while the back is pushed backward, while the front of the desk top plate 5 is raised. Accordingly, the vertical pedestal 41, which protrudes above the desk top plate in front of the desk, is inserted into the pedestal insertion hole 52 of the desk top plate. In addition, when the intermittent shaft 84 is pushed backward by the force applied from the upper portion as described above, the spring 852 of the spring pressing means which is installed between the pressing plate 851 of the spring pressing means and the drawer lower plate 21. ) Is compressed again. At this time, the hinge shaft 72 which interconnects the rear lower surface of the desk top plate 5 and the upper end of the rear platform 7 is moved to the rear of the long hole through the horizontal long hole 71.

When both rear lifting platform 7 is inserted into both vertical pipes 11 and the intermittent hole 82 formed at the upper end of the rear lifting platform 7 coincides with the through hole 81 of the vertical pipe, the spring is pushed. By the elastic force of the spring 852 constituting the means, the pressing plate 851 is rotated in the opposite direction to which it has been rotated so that the rotation shaft 83 is rotated back to its original position.

As a result, the interlocking shaft 84 on both sides of the rotary shaft 83 is inserted into and fastened to the through-hole 81 and the intermittent hole 82, and the rear platform is fixed, thereby maintaining a horizontal state again.
