In an elevator doorway door apparatus of a multi-speed type, a plurality of door panels are displaced forwardly and backwardly each other, and are movably supported in a transverse direction. During door closing, these door panels are arranged in an uneven step shape at the left and right, and an elevator doorway is closed. During door opening, the door panels move at different speeds in one direction toward the side of a door bag portion, and the doorway is opened. A closing member having a sealing material is provided at a side portion of one door panel with a high movement speed, and only during door closing, the closing member is brought into contact with a side portion of the other door panel to close a gap between the side portions. In this manner, the air tightness between the side portions of the door panels during door closing is well maintained without degrading the movement performance of the door panels, making it possible to enhance the noise shutout property and smoke shutout property.
