    Abstract: PROBLEM TO BE SOLVED: To reduce supply power and to miniaturize a door device by making drive load of a drive motor at the time of sliding of a door on a landing side in an opening direction substantially constant.
    SOLUTION: A spring mechanism 21 for sliding the door on the landing side in a closing direction is constituted of a winding drum 22, a wire cable 23 having one end part wound on an outer peripheral surface 27a of an outer peripheral wall 27 of the winding drum 22 via a guide groove 30 and the other end part drawn from the winding drum 22 locked on the door on the landing side, and a spiral spring 24 for energizing the door on the landing side to the winding drum 22 via the wire cable 23 in the closing direction. The outer peripheral surface 27a of the outer peripheral wall 27 is formed into a conical shape to variably form an outer diameter. A beginning part of the one end part of the wire cable 23 is locked on a maximum diameter part of the winding drum 22 to set a drawing portion of the wire cable 23 when closing the door to a minimum diameter part side of the winding drum 22.
