[Problem] To suppress displacement of a stopper in relation to a guide rail. [Solution] An automatic door device is provided with a guide rail for guiding a door in opening and closing directions, and a stopper attached to the guide rail. The stopper contacts the door so as to limit the movement of the door in the opening and closing directions at prescribed positions. Also, a detachment prevention means is provided configured so as to resist the moment at which the stopper is rotated, using the portion of the end part of the stopper that contacts the guide rail, the portion being positioned on the opposite side of the door, as a center axis.
