<P>PROBLEM TO BE SOLVED: To provide a shutter device capable of improving security by increasing rigidity of at least either of linear coupling members and slats of a shutter curtain in the closed state of the shutter curtain. <P>SOLUTION: A shutter device includes a shutter curtain 1 that is formed by juxtaposing a plurality of slats 6 along a height direction, and a winding body 2 for winding/unwinding the shutter curtain 1. The shutter curtain 1 comprises the plurality of slats 6, and linear coupling members 7 that are provided at the ends of the slats 6 so as to wind and unwind the slats 6, respectively. Rigidity increasing means for increasing rigidity of at least either of the linear coupling members 7 and slats 6 of the shutter curtain 1 in the closed state of the shutter curtain 1 is provided. <P>COPYRIGHT: (C)2012,JPO&INPIT |
