Abstract

PURPOSE:To enable an adjustment of position slidable upward and downwardly to be attained, perform a sliding movement on a frame by pulling a shelf toward an operator and enable it to be drawn by a method wherein a front surface of a frame is inclined slightly upward and can be moved up and down directly along a sliding groove. CONSTITUTION:As an operator's side of a frame 10 is lifted up, a stopper claw 13 fixed to the frame 10 is removed from a rack-like stopper groove 15 around a rotating axis of guide rollers 12 at both right and left ends arranged in a shaft 11. Then, the frame 10 holding a shelf 9 is moved up or down directly to a target position along a sliding groove 14a of a rail 14. When the shelf 9 reaches the target position, the operator's side of the frame 10 is returned back to its original horizontal position, resulting in that the stopper claw 13 is engaged with a rack-like stopper groove 15 and held there. In addition, when the shelf 9 is pulled forwardly and moved, it is slid on a lower flange 10e of the frame 10 and its position is set by a stopper 10f.
