SKELETAL COMPONENT FOR AUTOMOBILE AND FRONT PILLAR LOWER INCLUDING THE SAME

摘要

This front pillar lower outer (10) is provided with a curved site (13), a first site (14), and a second site (15), and it is envisioned that an impact load would be incurred along the direction of extension of the first site (14). The outer (10) is configured from joining a first member (11) disposed at the first site (14) side and a second member (12) disposed at the second site (15) side. The join line (L) of the two is disposed in a predetermined region between a first boundary (16) and a second boundary (17). The first boundary (16) is a line connecting the end (10f1) at the first site (14) side of a curved section at the curve inside and the end (10g1) at the first site (14) side at a curved section at the curve outside. The second boundary (17) is a line from the end (10f2) at the second site (15) side of the curved section at the curve inside extending in the direction of extension of the first site (14). The thickness of the first member (11) is thicker than that of the second member (12).
