PURPOSE: To prevent a door provided in a gate-cum-passage from being damaged and a passerby from being hurt. CONSTITUTION: A door device for gate-cum-passage comprises a case 3 which is installed along one side of a passage 1 and provided with a storing groove 2 extended in the vertical direction, and a door 4, the base end part 4a of which is supported on the case 3 in such a manner as to freely rotate, and which closes the passage in its horizontal attitude and is stored in the storing groove 2 in its upright attitude. A hinge part 6 for supporting a door main body 4b in such a manner as to freely rotate to the horizontal direction is provided on the base end part 4a of the door 4, and the hinge part 6 is provided with an energizing means for energizing the door 4 opposite in the horizontal direction in such a manner as to take an attitude intersecting perpendicularly to the passage 1. When the door 4 is put in the horizontal attitude to close the passage 1, even if a passerby passes in error or by force, a shock produced when the passerby hits against the door 4 is buffered by the energizing means provided on the hinge part 6, so that the door 4 is kept from being damaged and the passerby is kept from being hurt. |
