Claims

[Scope of utility model registration request]

It extends in the longitudinal direction of the vehicle body on the left and right sides of the lower surface of the vehicle body floor, and is formed in a box-shaped cross section, and the front horizontal part and the rear horizontal part are smaller in cross section than the intermediate horizontal part, and the front horizontal part is smaller in cross section than the middle horizontal part. In a side member in which a horizontal portion and a rear horizontal portion are vertically offset, a front buttful is erected within a first bent portion on the front side that is a bending point between the front horizontal portion and a front inclined portion continuous to the intermediate horizontal portion. Further, a rear buttful is erected in a second front bending part that is a bending point between the intermediate horizontal part and the front inclined part, and the front buttful and the rear buttfull are abbreviated to have a box-shaped cross section of the side member. The front buttress is erected so as to be closed, and the front buttress and the rear buttress are connected by a horizontally installed reinforcement, and the front buttress, the rear buttress, and the rainforth are
A reinforcing structure for a side member in a vehicle, characterized in that flanges formed on both sides are welded to inner walls of both side walls of the side member.
