Abstract:
An elevator door device is configured such that a pulley device has a pulley shaft and a pulley body. The center of rotation of the pulley body is tiltable relative to the pulley shaft. The pulley body is movable in the axial direction of the pulley shaft. The pulley body has a circular cylindrical intermediate section around which a belt is wound, a first flange section, and a second flange section. The outer diameter of the first flange section gradually conically changes from the intermediate section side toward the side opposite the intermediate section. The outer diameter of the second flange section gradually conically changes so that the second flange section is symmetric with the first flange section. The pulley device further has a first roller which is in contact with the outer peripheral surface of the first flange section, and a second roller which is in contact with the outer peripheral surface of the second flange section.
