PROBLEM TO BE SOLVED: To provide a rolling screen for a clean room which can control the release of dust. SOLUTION: When external force is exerted on the screen 22, the sliding part 37s of a cushioning member 37 which is engaged with a cushion spring 35 slides and makes a sliding spinning motion in a guide groove 40. The cushioning member 37 is formed of a sliding grade polyacetal resin of which the friction coefficient is smaller than that of a metal, and the amount of dust generated by the contact between the cushioning member 37 and the cushion spring 35 or the guide groove 40 is small. Because of this, the release of the dust in the clean room can be prevented. COPYRIGHT: (C)2010,JPO&INPIT
