PROBLEM TO BE SOLVED: To provide a screen that can flexibly cope with conditions for installation. SOLUTION: Curtain cloth 5 is hung on beams 2 supported by poles 1 and the beams 2 are allowed to freely expand and contract by freely slidably inserting an inner pipe 7 into an outer pipe 6. A flexible member 9 intervenes in a part of each beam 2. The screen can be used as it is set to the required width with the expansion and contraction of the beams 2, and the direction of a viewing field to be blocked can be adjusted by varying the degree of curvature of each flexible member 9.
