Abstract:

A front pillar lower outer (10) includes a bent portion (13), and a first region (14) and a second region (15), and is a skeletal component for automobile that is assumed to receive a collision load along the extending direction of the first region (14). The outer (10) is constituted by attaching a first member (11) that is arranged on a first region (14) side, and a second member (12) that is arranged on a second region (15) side. An attachment line (L) of the both members is arranged in a predetermined zone between a first boundary (16) and a second boundary (17). The first boundary (16) is a straight line that connects an end (10f1), on the first region (14) side, of an arc-shaped portion on the inside of the bending, and an end (10g1), on the first region (14), of an arc-shaped portion on the outside of the bending. The second boundary (17) is a straight line that runs from an end (10f2), on second region (15) side, of the arc-shaped portion on the inside of the bending, along the extending direction of the first region (14). The plate thickness of the first member (11) is larger than the plate thickness of the second member (12).
