<p>PROBLEM TO BE SOLVED: To improve access to an article housing box without reducing the amount of loading by attaching a holding member for holding the article housing box to a truck main body so as to be movable between first and second positions. SOLUTION: A mobile shelf 13 is positioned in a first position and supported from the bottom by a lowering stopper 18, a first article housing box is placed thereon and then picking is performed. After the end of the picking, while the lowering stopper 18 is retreated, the mobile shelf 13 is moved to a second position by pushing the upper part of the first article housing box. During this movement, the end part of the mobile shelf 13 pushes the slope of the folded part of a locking plate 18 to cause the locking plate 18 to take a retreating attitude and, when the engagement with this slope is released, the mobile shelf 13 is locked again by the locking plate 18. In this state, the first article housing box is directly supported on a roller 4 and its bottom surface is placed away from the mobile shelf 13.
