Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fire shutter which can be rolled into a roll having a reduced diameter when the shutter is rolled around a drum, is provided with an actuator having a smaller capacity and has a heat insulation layer to be expanded at the time of a fire and hardly damaged and coming off.

The clothes are horizontally connected with one another by a connecting means 13 with an appropriate space in the vertical direction. COPYRIGHT: (C)2006,JPO&NCIPI
