Abstract
A reinforcement, joined by welding to a vehicle structural member having a closed cross section, comprising a curved section at least in part of its length, a top wall having opposite edges, and a pair of lateral walls extending from the edges to form ridge lines, wherein the top wall and the lateral walls form a U-shaped cross section. The lateral wall includes a base surface and a plurality of welding projections at intervals along its length, each welding projection having a raised surface for welding. Each welding projection is raised from the base surface of the lateral wall toward the vehicle structural member. The lateral wall further includes a bead between the welding projections within a curved section to prevent or suppress wrinkles from forming during press forming. The bead is raised from the base surface of the lateral wall toward the vehicle structural member.
