  • the reinforcing member 3 has a different posture from the reinforcing member 3 in the third embodiment, and is arranged upside down.
  • the protruding direction of the flange portion 32A of the reinforcing member 3 faces the positive side in the Y-axis direction
  • the protruding direction of the flange portion 32B faces the lower side (negative side in the Z-axis direction).
  • the vehicle body structure 1 as described above has an effective configuration when it is desired to join the reinforcing member 3 to the roof side outer 93.
  • each part constituting the vehicle body structure and the reinforcing member can be replaced with an arbitrary configuration capable of exhibiting the same function. Further, any component may be added.
  • the vehicle body structure, the reinforcing member, and the method for manufacturing the reinforcing member of the present invention may be a combination of any two or more configurations (features) in each of the above-described embodiments.
  • the roof side rail member 2 to which the reinforcing member 3 is joined becomes the roof side inner 92 in the first embodiment and the third embodiment, and becomes the roof side outer 93 in the second embodiment and the fourth embodiment.
  • the case is not limited to these, and may be used as a side outer 91.
  • the reinforcing member 3 is arranged inside the roof side rail 9, but is not limited to this, and may be arranged outside the roof side rail 9.
  • the thickness of the flange portion 32 can be appropriately adjusted by the molding apparatus 8. As a result, the joint portion of the flange portion 32 can be, for example, between the roof side inner 92 and the roof side outer 93.
