Abstract
An automobile frame component includes a closed section constituted by welding a flange portion to a panel part, wherein when a welding position coordinate is represented in a coordinate system in which an end of a contact position between the flange portion and the panel part is assumed as 0, and a flange outer end side of the flange portion is assumed as negative (−) whereas a vertical wall side is assumed as positive (+), and when a radius of a circular arc-like portion connecting a vertical wall portion and the flange portion in the substantially hat-like shape is denoted as R (mm), and a weldable gap amount is denoted as a (mm), a welding position X represented by the following formula is continuously welded using a one-side welding method:+√(2)≥>1.5 where≥2.
