Vehicle parting portion structure and manufacturing method thereof

A method of manufacturing a vehicle parting portion structure, the method comprising:

• a first process of folding a first vehicle outer panel member to form a first outer panel configuration portion and a second outer panel configuration portion with a first fold line interposed therebetween;
• a second process of folding the second outer panel configuration portion along a line intersecting the first fold line at an acute angle to form a third outer panel configuration portion by part of the second outer panel configuration portion between a second fold line along the line and the first fold line, and to form a fourth outer panel configuration portion by another part of the second outer panel configuration portion such that the fourth outer panel configuration portion is contiguous to the third outer panel configuration portion with the second fold line interposed therebetween, a V shaped bead being formed by a portion of the first outer panel configuration portion and a portion of the fourth outer panel configuration portion such that the bead has a ridge line extending from a point at which the first folding line and the second folding line meet;
• a third process of disposing a second vehicle outer panel along one of the first fold line or the second fold line and at a position forming a first parting portion between the second vehicle outer panel and the third outer panel configuration portion;
• and
• a fourth process of disposing a third vehicle outer panel along the other of the first fold line or the second fold line and at a position forming a second parting portion between the third vehicle outer panel and the third outer panel configuration portion, and at a position further forming a third parting portion between the third vehicle outer panel and the second vehicle outer panel, an acute angle corner portion being formed at a location at which the first parting portion and the second parting portion meet, and the bead being disposed at the acute ankle corner portion.
