Claims

[Scope of utility model registration request]

A back bone reinforcement is superimposed on the back bone formed on the floor pan, and one end of a cross member provided on the floor pan is fixed to the back bone by spot welding, and the seat frame is attached to this cross member. In a vehicle body structure connected by a connecting means, a part of either the floor pan or the back bone reinforcement located above the side of the back bone is bulged out to the side to connect the cross. It is formed in a protrusion with a closed cross section located inside the end of the member, and protrudes from the lower surface of this protrusion or the lower surface of a portion of the cross member near the protrusion to the upper surface of the end of the cross member. A vehicle body structure characterized by providing a coupling means for coupling a seat frame.
