The present invention relates to a door device having an airtight function which improves the airtight performance between a lower side of a door and an entrance port, even having no door frame on the entrance port, thus easily performing the delivery of goods and remarkably raising the airtight performance of a warehouse facility. According to the present invention, a door device having a door for opening and closing an entrance port of a warehouse facility is configured wherein the warehouse has no door frame on the entrance port so that the indoor space and outdoor space are connected to each other through the ground between the entrance port, and the door device includes a first sealing means adapted to allow the door to be brought into close contact with the entrance port if the entrance port is closed by the door to air-tightly seal the space between the door and the entrance port; and a second sealing means adapted to allow the door to be brought into close contact with the ground if the entrance port is closed by the door to air-tightly seal the space between the door and the ground. |
