Abstract (en)
[origin: EP2657174A1] There is provided a door operator of an elevator that can restrain the displacement of a door properly even when an external force is applied to the door on account of wind pressure or the like. The door operator includes a hanger roller and a stabilizing roller that are provided rotatably on a door hanger, a support body for supporting a door rail, and a displacement restraining device provided on the door hanger. The displacement restraining device is provided to restrain the door from being displaced to the axial direction of the hanger roller. The displacement restraining device includes a first guide roller that rotates while being in contact with one side surface of a part of the support body along with the opening/closing movement of the door and a second guide roller that rotates while being in contact with the other side surface of the part of the support body along with the opening/closing movement of the door.
