Abstract

A structure for a side portion of a vehicle body achieves required side collision resistance without an increase in the plate thickness of both a center pillar forming member (23) and a side sill forming member (21) and without an increase in the number of points of spot welding. The center pillar forming member and the side sill forming member are spot welded at welding points arranged in a horizontal row, and a pair of beads (23) parallel to the welding points is provided directly above the welding points. When a side collision impact is applied to the beads, they elongate in the vertical direction to successfully absorb the impact.

Description

technical field [0001] The present invention relates to a side body structure of an automobile, and more particularly to a structure of a joint portion between a center pillar component and a side sill component of the side portion of the vehicle body. Background technique [0002] As a side body structure of an automobile, there is known a structure in which a center pillar component and a side sill component are joined to the side sill component at its lower end by spot welding or the like (for example, refer to patent documents 1). [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 7-267140 [0004] In the event of a side collision, a large load will act on the junction (junction) between the center pillar component and the side sill component. Therefore, in order to be able to withstand the load, it is considered to increase the plate thickness of these components, Or measures such as increasing the number of spot welding spots between the center pil...
