PROBLEM TO BE SOLVED: To provide a fireproof shutter which forms a fire compartment by closing a plurality of horizontally juxtaposed main sheet bodies wherein a lock pin and a retainer plate with a formed lock hole are provided between auxiliary sheet bodies for closing a gap between side edges of the adjacent main sheet bodies, and which makes the lock pin surely fitted into the lock hole. SOLUTION: A first guide roller 9 for the main sheet body 2 which is provided with a retainer plate unit 12 is provided between a main winding shaft 3 and a sheet feeding port 8a. Second and third guide rollers 10 and 11 for an auxiliary sheet body 6 which are located in the upper and lower positions of the roller 9 and provided with a lock pin unit 13 are provided between an auxiliary winding shaft 7 and the port 8a. A linear movement locus with a length greater than the vertical length of the unit 12 which is expanded toward its upside is formed above a position in which both the sheet bodies 2 and 6 overlap each other.
