Storage structure

A storage structure for storing articles and having outer walls in side periphery thereof comprising:

• a plurality of columns spaced apart from each other along a spaced-apart direction;
• an outside surface panel configured to be located between two mutually adjacent columns to form a part of an outer wall;
• an outward-side pressing member configured to be removably attached to a first target surface of a column, the first target surface being an outward side surface of the column;
• and
• an inward-side pressing member configured to be removably attached to a second target surface of the column, the second target surface extending at an angle with the first target surface;
• wherein the outside surface panel has a panel width which is less than an inter-column separation distance which is a dimension, along the spaced-apart direction, of a space formed between the two mutually adjacent columns,
• wherein the outward-side pressing member and the inward-side pressing member are configured to cooperate with each other to apply pressure to the outside surface panel from a front side and a back side of the outside surface panel,
• wherein the inward-side pressing member is configured to be capable of being attached to and removed from the column by a worker by directly and manually operating the inward-side pressing member using fingers,
• wherein the inward-side pressing member is configured to rotate about its own axis while attached to the second target surface, and
• wherein the inward-side pressing member has a main body portion having a pressing surface which is configured to contact the outside surface panel and which is generally formed in a shape of a part of a sphere or in a shape of a circular-arc surface.
