To provide a panel expansion device in which members are constituted of four or more panels and the panels can be expanded in a direction between the members mounted with the panels.SOLUTION: The panel expansion device comprises a first constitution member 2 configured so that a plurality of panels 4, 5 and 6 overlap with one another and a second constitution member 3 configured so that a plurality of panels 7, 8 and 9 overlap with one another. The first constitution member 2 is connected with a first expandable link member 14, the second constitution member 3 is connected with a second expandable link member 15, and the constitution members 2 and 3 can be expanded respectively by expansion of the link members 14 and 15. The first constitution member 2 and the second constitution member 3 can be turned relatively with rotating shafts 11 and 12 as centers, and are connected to each other detachably. The first link member 14 and the second link member 15 are connected to both end parts of connection link arm members 34 and 35 respectively through a universal joint, and the first link member 14 and the second link member 15 can be separated from each other.SELECTED DRAWING: Figure 2
