An automobile door guard for a vehicle is provided to operate a guard motor placed in a weight and to lift up a guard bar to a projected part of the door of the vehicle so as to preclude contact between vehicles during the parking. A door of a vehicle has an automatic guard frame(1) and a protection guard bar(3). The guard bar is lifted up by operating a guard motor(5) installed in a weight(4) which is inserted in a pipe of a protection guard support(2). When a bolt(8) is operated, a nut(10) is far from the screw bolt. Center of gravity is toward the rear end of the protection guard support on a connecting bolt(11). When the bolt is reversely-rotated, a limit switch(7) is contacted with the nut.
