<P>PROBLEM TO BE SOLVED: To provide a fixing structure in which a flame block performance can be ensured even in the case where a fixing target such as a transmitter is fixed in a fireproof structure such as a fireproof shutter device, or to provide a fixing target which can be fixed in such a fireproof structure while ensuring a flame block performance. <P>SOLUTION: A fixing structure for fixing a fixing target to a fireproof structure comprises fixing screws 30 for fixing a transmitter to a shutter curtain 12 and a presser 40 which presses the transmitter 22 away from the shutter curtain 12. In the case where the fixing screws 30 or the presser 40 is heated with heat in the case of a fire, the presser 40 presses the transmitter 22 with a pressing force equal to or more than a fixing force of the fixing screws 30. <P>COPYRIGHT: (C)2013,JPO&INPIT |
