PROBLEM TO BE SOLVED: To provide a door stopper which stops a rotating door even when a flap is inclined in an upper direction, thereby detecting abnormality in engagement between the flap and a flap receiver, and prevents the flap from warping. SOLUTION: The door stopper is formed by arranging the flap receiver 2 at a lower end of a rotating side edge 11 of the rotatable door 1, and arranging the flap 4 which is vertically rotatable, on a floor 3 below a rotational locus of the flap receiver 2. The door stopper is comprised of a flap warp preventing portion 7 formed of an auxiliary abutting surface 71 and an auxiliary lower surface 12. The auxiliary abutting surface 71 extends almost upward from an edge 61b of an engaging lower surface 61 of the flap receiver 2, on an opposite side to an engaging abutting surface 62 of the flap receiver 2. The auxiliary lower surface 72 extends from an upper edge 71a of the auxiliary abutting surface 71 in a direction opposite to the engaging lower surface 61.
