Säulen-Verbindungsstruktur für einen Kraftwagen

摘要

A side sill is formed into a stair-like configuration with step portions having in turn upper surfaces of lower and upper steps and an intermediate rise portion rising from the step portion so as to reach the step portion of the upper step. A lower end of a center pillar having substantially an angular 8-shaped cross-section is cut in conformity with the stair-like configuration of the side sill. The cutting of the center pillar exposes the intermediate wall, and the exposed intermediate wall is then brought into abutment with the rise portion, whereupon abutment portions so produced are welded together to thereby get the side sill and the center pillar integrated with each other.
