<p>PROBLEM TO BE SOLVED: To stably hold a display body in a self-supporting state by surely attaching a cylindrical body and a supporting body by an easy operation. SOLUTION: By self-shape holding power of a cylindrical body 3 which acts when the cylindrical body 3 is attached on a supporting body 2, a hole part 9a of the cylindrical body 3 is engaged with an engaging part 8a of the supporting body 2, and the cylindrical body 3 is held attaching on the supporting body 2 so that an axial movement of the cylindrical body 3 is restrained. Accordingly, the cylindrical body 3 is easily attached on the supporting body 2 by using the self-shape holding power of the cylindrical body 3, and can be stably held in a self-supporting state.</p> |
