SOLUTION: This shutter has a pair of guide rails 3 brought into close contact with both left and right side walls and supported oscillatably to make a lower part jumped up frontwards and rearwards, a smoke blocking sheet 6 of which the left and right end edge parts are supported by the guide rails 3, and elevated therealong, a means for energizing a tip part of the sheet 6 to go down, an upper seal member 28 and a side end seal member 5 for blocking a clearance between an opening 27 formed in a ceiling part and the sheet 6 attached to the guide rails 3, a lower seal member 9 for blocking a clearance between the sheet 6 attached to a tip of the sheet 6 and a floor face 13, a means for restricting limitingly the frontward oscillation of the guide rails up to fixed external force, and a rolling device 2 installed in the ceiling part for rolling the sheet 6 to be stored. The shutter is preferably provided with a rearward oscillation preventing means for the guide rails, and a locking mechanism 30 further. COPYRIGHT: (C)2004,JPO
