<p>A lower arm 11 for an automobile which is formed by pressing a metallic plate comprises a first horizontal portion 15 extending horizontally when attached to a vehicle body, perpendicular portions 16a, 16b formed by bending downwardly peripheral edges of the first horizontal portion 15, reverse flanges 17a, 17b, 17c formed by bending inwardly lower edges of the perpendicular portions 16a, 16b and a second horizontal portion 20 provided in the vicinity of a vehicle body mounting portion 13 in order to project upwardly from the first horizontal portion 15. The height of a center of bending for vertical bending load is raised higher by the formation of the second horizontal portion 20 so that a distance from the center of bending to the reverse flanges 17a, 17b, 17c is increased, whereby tensile load and compressive load acting on the reverse flanges 17a, 17b, 17c is reduced. <IMAGE></p> |
