PROBLEM TO BE SOLVED: To provide a shutter device by which a fully closed state of a shutter curtain can be obtained even when the parts of a sheet inserted into the right and left guide members do not smoothly move downward. SOLUTION: In the shutter device, the shutter curtain 12 is moved to be opened and closed in a vertical direction by being guided by the guide rails 5, which is the right and left guide members, and a lower part of the curtain 12 on the closing side, at least, is formed to be a sheet part 30 which is formed of a sheet member. The sheet part 30 is formed to include first and second sheet members 31, 32. The whole of the first sheet member 31 is exposed from the guide rails 5 and has an area larger than that of the second sheet members 32. The second sheet members 32 arranged on the right and left guide rails 5, respectively, comprise the parts inserted into the guide rails 5 and the parts exposed from the guide rails 5. The first and second sheet members 31, 32 have overlapping parts 31C, 32C mutually overlapping in a direction of the thickness of the curtain 12. COPYRIGHT: (C)2009,JPO&INPIT |
