PROBLEM TO BE SOLVED: To provide a method and a device for preventing a door from twisting in its opening motion over a long term. SOLUTION: When a stop member 2 provided on an upper surface of a door end side of a first door A begins to project upward by interlocking with the motion of a second door B being opened from the first door A to expand the first door A near the final position, a bounding motion accompanying the opening motion of the first door A is prevented, and the door end side is surely fixed on an upper frame by inserting the stop member 2 in an engaging hole 51 provided on the upper frame F, etc., of a door stop to prevent the first door from twisting.
