摘要

In a vehicle body structure, in which a roof sides of rails section 2 of a side surface portion of a vehicle body 1 and a roof reinforcement 9 are connected by a gusset plate g, in order to suppress that a section 4 of a central column into an elevator car side occurs when a large load is introduced from one side of the vehicle, is a notches section g17 provided on the gusset plate g. This is suppressed, that, when the large load on the section 4 of the central column is introduced from the side of the vehicle, the gusset plate g thus, by way of a rotation of the roof sides of rails section 2 is deformed by bending, that a rotation moment m which, by means of the rotation of the roof sides of rails section 2 is brought about, and acts on the roof reinforcement 9, as a result of which is suppressed, that the portion 4 of the central column in the cab side entry.
