<p>A door device for an elevator, in which a flexible air-tight member (6) extended in the opening/closing direction (A) of a door body (1b) is attached to the door body (1b) so as to be in pressed contact with a floor-side surface (4b) and, as the door (1) is opened and closed, the air-tight member (6) slides on the floor-side surface (4b) while being in pressed contact with the floor-side surface (4b). A low friction section (6b) is formed on that surface (6a) of the air-tight member (6) with which the floor-side surface (4b) is in pressed contact.</p>
