PROBLEM TO BE SOLVED: To provide a screen capable of excellently maintaining flatness of a screen surface. SOLUTION: The screen 1 is equipped with a pressing member 6 moving between a base part 3 and a pull-up member 4. The pressing member 6 is equipped with an extension member 7 extending in parallel with the base part 3 and the pull-up member 4, and spreading parts 8 provided at both ends in the extending direction of the extension member 7 and spreading both ends of a screen main body 2 to the outside. The spreading part 8 is equipped with a pair of pressure rollers holding both sides of the screen main body 2 in between, and a roller support part supporting the pair of pressure rollers turnably with a shaft nearly parallel with the extending direction of the extension member 7 as the center, and attached turnably by a predetermined angle with a shaft orthogonal to the screen surface of the screen main body 2 relative to the extension member 7 as the center.
