PROBLEM TO BE SOLVED: To provide a unit assembly structure of a system ceiling which is easily mounted on a unit in an assembled condition, and scarcely occurring a step or a clearance at a butted part. SOLUTION: A substantially rectangular frame is mounted on its short side between T-bars 1 which are suspended from a building skeleton and opposite to each other. A short member 11 on the short side of a frame 2 is formed of an elastic material at the storable height between a horizontal piece 5 at a lower end of the T-bar 1 and a head portion 6, and has an engagement part 21. A perpendicular piece 7 between the horizontal piece 5 of the T-bar 1 and the head portion 6 is engaged with the engagement part 21 in a projecting condition from the perpendicular piece 7, and a screw 10 to attract the short member 11 toward the T-bar 1 in an elastically deformed condition by tightening the engagement part 21 to the perpendicular piece 7, and to substantially and closely attach the short member to the perpendicular piece 7 is provided. |
