PROBLEM TO BE SOLVED: To provide a shutter device in which the number of slats can be changed easily.SOLUTION: A shutter device comprises a support member 3 for engaging a slat 1 to concatenation members 4 which are positioned in both right and left end portions. The concatenation member 4 includes en engage section 42 to which the support member 3 is engaged, and a slot insert section 43 which is adjacent to a slot 41 opening in the vicinity of the engage section 42 and inserted into a slot 41 of the other link 4. The slot 41 includes an enlarged part 411 in which a portion close to the engage section 42 is opened larger than the others. The slot insert section 43 includes a root part 431 which protrudes in a direction to be inserted into the slot 41 of the other concatenation member 4, and a bevel part 432 which is positioned in a direction to be inserted from the root part 431 into the slot 41 and has a cross-sectional shape larger than the root part 431 and sized to pass through the opening of the enlarged part 411 and not to pass through any other than the enlarged part 411 of the slot 41. A support engage section 33 is joined to the engage section 42 and narrows the opening of the enlarged part 411 in the slot 41 so as not to pass the bevel part 432 therethrough. |
