A door panel guide device for a defense door is provided to prevent the separation of a transfer chain transmitting a door panel and to implement the opening and closing of a door safely by adopting a separation prevention unit guiding the transfer chain. A door panel guide device for a defense door comprises a guide piece(24), a fixing bracket, and a separation prevention unit. The guide piece transfers a door panel such that the lower part of the door panel is tilted with respect to the upper part of another door panel, by guiding a bottom guide roller of the door panel to a supporting panel(21) from the upper side of a guide rail(12). The fixing bracket is installed on the upper part of the supporting panel to correspond to a first sprocket wheel(S1). The separation prevention unit for preventing the separation of a transfer chain passed by the first sprocket wheel from the fixing bracket is installed to be adjustable in height. |
