The fire door sealing member according to the third embodiment of the present invention includes a third partition part c3 instead of the first partition part c1 in the configuration of the fire door sealing member according to the first embodiment. The third partition part c3 partitions the space part e and supports the contact part 110, and prevents the support part 120 and the insertion part 130 from being damaged from being pressed by the door d. To this end, the third partition portion c3 partitions the space portion e in an oblique direction. In detail, the upper end of the third partition part c3 is connected to the curved portion of the support part 120 having a semicircular cross section, and the lower end is connected to one side of the insertion part 130. That is, referring to FIG. 11, the upper end of the third partition part c3 is connected to the left curved portion of the support part 120 and the lower end is connected to the right side of the insertion part 130. Accordingly, the third partition portion c3 partitions the space portion e in the diagonal direction. However, the connection form of the third compartment c3 shown in FIG. 11 is not limited thereto. That is, the third partition c3 may be horizontally symmetrical with the third partition c3 illustrated in FIG. 11, and may be connected to the support part 120 and the insertion part 130. The three partitions c3 may be connected to the support part 120 and the insertion part 130 in parallel or crossing each other. On the other hand, the space part e is partitioned into the 1st space e3 and the 2nd space e4 by the 3rd partition part c3. Through this, the support part 120 and the insertion part 130 may distribute the force applied through the third partition part c3 provided diagonally in the process of being pressed downward by the door d. Here, since the support part 120 and the insertion part 130 are connected by the third partition part to receive a force integrally, the force generated by the pressing of the door d may be more dispersed. In addition, the upper end of the third partition (c3) is connected to the curved portion of the support portion 120, the third partition (c3) can support the upper side from the lower side of the contact portion (110). That is, the contact part 110 may be supported upward through the third partition part c3, and thus the third partition part c3 shares the force transmitted to the lower side of the contact part 110, thereby causing the door d ) Can be prevented from being damaged by pressurization.
