<P>PROBLEM TO BE SOLVED: To provide a screen for improving flatness of a screen body. Ž<P>SOLUTION: The screen 1 includes the screen body 2, a rewinding shaft 3, a holding member 4, a plurality of tubular members 5, two wires 6, a pantograph mechanism 7, and a body tension applying mechanism 8. The screen body 2 includes two crossing sides A respectively crossing with two sides held by the rewinding shaft 3 and the holding members 4, and has a shape of rotational symmetry in a thread winding shaft shape. The tubular members 5 are arranged along the respective crossing sides A, and are formed in a tubular shape passing through along an extending direction of the respective crossing sides A. The wires 6 are supported at both ends so as to locate on an outer side of the respective crossing sides A, and are inserted in the respective tubular members 5. The pantograph mechanism 7 applies tension on the wires 6 along the extending direction of the respective crossing sides A. The body tension applying mechanism 8 applies the tension along the extending direction of the respective crossing sides A to the screen body 2. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
