To provide a kind of device for continuously supporting stacked metallic plates as they are, and preventing " floating " of the metallic plate stacked on the uppermost part.

An upper bolt of the metallic plate is constituted, so as to be movable in a through-hole of the metallic plate, and so as to be movable in the pallet direction. Before stacking, a guide cartridge 6 is fitted in a hole 7 of a pallet 4, and a through-pointed end part 8 is fitted in the hole when a through-bolt 5 moves downward. The through-bolt 5 moves the guide cartridge 6 downward. The through-bolt 5 is separated from the guide cartridge 6 when an upper angle of the guide cartridge 6 becomes a state of projecting to the upper side of the metallic plate 2 when moving upward.
