Pillar structure in car

Abstract

Abstract PURPOSE:To improve the strength of a body by forming a closed cross section using pillar inner and outer and partitioning a side sill and the inner space of a pillar using a stage-reduced surface that is provided between the side sill section of the pillar inner and the pillar section. CONSTITUTION:A closed cross section is formed using a pillar inner 3a that extends the outer member of a side sill 2 upward and a pillar outer 3b that overlaps with the pillar inner from outward. Besides, the inner space of the side sill and the inner space of the pillar are partitioned by providing a stage-reduced surface 6 in which the pillar section 3 is inside between the side sill section 2 of the pillar inner 3a and the pillar section 3. As a result, the coupling of the pillar 3 and the side sill 2 is reinforced and the strength and rigidity of a body can be improved. Furthermore, a cab side frame outer 1 consisting of the side sill section 2, front pillar inner section 3a, rear fender section 4, lane rail outer section 5, etc. can be formed integratedly and workability can be improved.
