Abstract

A packaging unit includes a lower cushioning material; middle cushioning materials each one of which is interposed between storing objects in corresponding one of two rows in an upper deck and a lower deck; upper cushioning materials; and a vibration absorbing unit provided on a bottommost portion of a container. The vibration absorbing unit includes a first flat plate, a second flat plate, and elastic bodies. The center of each of the elastic bodies is outside a centroid of corresponding one of the storing objects with respect to the center of the two rows of the storing objects. A distance between the center of each of the elastic bodies and the centroid of corresponding one of the storing objects in the width direction is in a range from 2% to 8% of a maximum outer diameter of the elastic body.
