The front body of an automobile is characterized by the construction that an opening part(11) of a length plate(10) formed by a sectional shape of " D " is consolidated through a welding process of an external length looped plate(12) of a straight belt shape which is formed by a length butt welding of both ends thereof and of an external length looped plate(13) of a bending belt shape, and in its inner side, an internal length looped plate(14) of the straight belt shape is folded then welded; that a plate pillar(15) of a square shape is flange-welded in one end's lower part of the length plate(10), and on its upper side, a front extension length plate(16) of a slanted step shape is partially butt welded in a length direction, and in another side lower part of the length plate(10), one end of a front support length plate(17) based on a rice scoop shape is welded, then on its upper face, the front extension length plate(16) is partially welded, and simultaneously one end of a bottom reinforcement plate(19) is welded so as to be horizontally set; and that on an upper face of the length plate(10), an engine mounting part(20) is formed by welding an engine mounting bracket(21) arranged on the upper face thereof, thereby absorbing and damping an impact force activating to a car body in a case of an impact occurrence through a structural strength and also largely reducing a warpage or rolling phenomenon of vehicles.
