<P>PROBLEM TO BE SOLVED: To simply exchange a roller without replacing the entire shutter body. Ž<P>SOLUTION: A roller 10 provided outside the side edge 9 of the shutter body 4 is rolled on and freely slidably mounted onto a guide rail 5. The taking-in/out part 27 for exchanging the roller 10 formed larger than the roller 10 is provided to the guide rail 5. The gap 28 between the guide rail 5 and the tip end surface 15 of the shaft 12 is formed larger than the roller 10. The roller 10 is removed from the shaft 12 within the guide rail 5, allowing the roller 10 to be taken out or also taken in through the gap 28, further through the taking-in/out part 27.
