Cushioning member, shock protection device, and portable information equipment using the same

摘要

A cushioning member includes a first plane, an opening opened to the first plane, and an air storage for storing air formed from the opening to an inside of the cushioning member. When a shock load is imposed on the cushioning member, the air in the air storage is compressed, and the first plane is deformed by the pressure of the compressed air to form a gap. A part of the compressed air flows out of the air storage through the gap. This structure provides a high shock-cushioning effect.
