<p><P>PROBLEM TO BE SOLVED: To provide a shutter device which is advantageous to secure silence by restraining the occurrence of abutting sound of slats. <P>SOLUTION: An operating body can be switched into an engaging position where it is engaged with at least part of a moving slat 6 to turn the slat 6 into an open attitude and to form an opening between the slat 6 and the adjacent slat 6, and into a retreat position where it is not engaged with the moving slat not to turn the slat into the open attitude. A guide part 100 guides the length direction end of the slat 6 released from winding of a winding body, to a guide passage 51. A displacement restraining part 9 restrains the slat 6 from being displaced in an open direction (a direction of an arrow mark a1) when the length direction end of the slat 6 moves toward the guide passage 51 from the guide part 100. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
