To direct a large number of workpieces to the same direction on one face, and stock them at a good space efficiency.

This stocker comprises a chute 20 having a slope, through which a workpiece 1 slips down; and rods 30 arranged at a predetermined space from a terminal end of the slope and approximately in parallel to the slope. A distal end of the rod 30 is inserted in an cavity part of the workpiece 1 slipping through the slope of the chute 20 and projecting from the terminal of the slope, and furthermore, the workpiece 1 slips down while being hooked to the rod 30, so as to skew the workpiece 1 with the rod 30 and stock it.
