When the user lifts the movable bottom plate 46 from the first position P1 to the position on the way to the second position P2, the repulsive force of the biasing member 66 overcomes the weight of the movable bottom plate 46, and the biasing member 66 moves against the desk 15. The movable bottom plate 46 is biased inwardly (direction from the first position P1 toward the second position P2) so as to be retracted. As a result, the movable bottom plate 46 is semi-automatically pulled into the desk 15 while moving from the first position P1 to the second position P2.

At this time, as shown in FIG. 10 , the first arm 63 rotates upward around the rotation shaft 62 , and the second arm 64 rotates so as to overlap the first arm 63 . Therefore, when the movable bottom plate 46 is at the second position P2, the first arm 63 and the second arm 64 are arranged to form an inverted V shape. When the movable bottom plate 46 moves to the second position P2, the movable bottom plate 46 hits the projecting piece 43 and stops. This completes the movement of the movable bottom plate 46 to the second position P2.

When the user wants to use the desk 15 again, the user puts his or her finger on the chamfered surface 52A of the second end 52 of the movable bottom plate 46 and moves the movable bottom plate 46 toward the first position P1. Rotate. The movable bottom plate 46 overcomes the repulsive force of the biasing member 66 by its own weight on the way from the second position P2 to the first position P1. After that, the movable bottom plate 46 moves to the first position P1 by its own weight. The user can use the desk 15 at the first position P1.
