PURPOSE: To prevent the collapse of stackable articles and the slippage from a fixed position, and allow the automatic putting in and out.

CONSTITUTION: A load collapse preventing guard 4 assembled and formed so that rice bags 3 stacked in six stages in one section 2 can be supported by horizontal struts from the four side surfaces in the center of each vertical height position is provided in a building 1, and a carrying device longitudinally and laterally movable for performing the stacking and putting in and out of the rice bags 3 by lifting up and down the rice bags 3 from above is provided on the ceiling part of the building 1. The load collapse preventing guard 4 for supporting the rice bags 3 from the side surface is provided, whereby the rice bags 3 can be stacked without causing a load collapse, and further, the rice bags 3 are placed in a fixed position, whereby they can be automatically put in and out without error on the basis of a preliminarily stored coordinate. The load collapse preventing guard 4 can be simplified.
