Abstract:
In a metal enclosure having a left side wall, a top wall, a right side wall and a bottom wall, at least two adjacent walls among these four walls are formed by folding a single plate as a starting material along predetermined folding lines and closed U-shaped ribs extending substantially perpendicular to said folding lines are formed by folding said walls. Each of said ribs has two rib walls extending in the longitudinal direction of said rib and one of the two rib walls at said front end of each of the two ribs extending toward said folding line is formed longer than the other. One rib wall thus extending longer than the other of said two front ends are fitted together. The connection of said two ribs is accomplished by spot welding said fitted rib walls.
