    • PURPOSE:To prevent a passage from being closed by a chair which is left and the reduction of space by installing an automatic rotary accommodating mechanism for accommodating a seat into under a deck and an elevator mechanism and automatically accommodating the seat below the deck when the seat is not used. CONSTITUTION:A fixed plate 5 is integrally installed at the intermediate part of a leg rod 2 supporting the deck 1 of a single pedestal desk, and a side feeding screw 11 having a handle 12 at the lower edge is installed on the fixed plate 5. A cylinder device 7 having a projecting plate 10 is fitted on the leg rod 2 above the fixed plate 5, and a nut 21 is screwingly fitted on the side feeding screw 11. The cylinder device 7 is vertically raised and lowered along the leg rod 2 by the side feeding screw 11 by the turning operation of the handle 12. A rotary cover 9 fitted on the leg rod 2 is fitted in the upper part of the cylinder device 7, and a torsional coil spring 8 which is wound on the leg rod 2 whose one edge is fixed on the bottom surface and the other edge is fixed on the upper surface of the rotary cover 9 is installed in the cylinder device 7, and an automatic rotary accommodating mechanism A is constituted. When a seat 3 is not used, a rotary arm rod 4 is engaged with a stopper 14 fixed on the cylinder device 7 or the seat 3 collides with a stopper 13.
