In a bracket to secure a door impact beam, there are the fixed part(10a) on the door body(1) and the inner part(10d) having inner surface(10c) to fix the impact beam(3). The one side of the inner part(10d) has several toruses(10e) being protruded to the circle of the inner surface(10c). The impact beam(3) is fixed on the ending part of the inner surface(10c) without a torus. If car crash happens on a side of an automobile, the impact power is transmitted to the impact beam(3) which received the power coming in the automobile. Because the one side of the impact beam(3) is secured with the ending part of the inner surface(10c) of the bracket and the inner part(10d) received the power as the arrow mark of the third map, the toruses(10e) in the inner part(10d) are straightened and the impact power is reduced firstly. The transformation amount of the impact beam and the door is reduced awfully.
