Beschreibung
Zusammenfassung:	A vehicle floor frame provides improved ride quality and energy absorption. A wall section opposes a lower surface of a floor panel; an outer wall section extends from an outer end portion of the wall section toward the floor panel; an inner wall section extends from an inner end portion of the wall section toward the floor panel; and a hole and a bead reduce a dimension of the wall section when an impact load is applied from an outer side in a vehicle width direction. A nut plate in a closed cross section of the floor frame includes lateral wall fixed sections respectively fixed to the outer wall section and the inner wall section; an opposing wall fixed section fixed to the wall section; and deformation promoting sections configured to reduce a dimension in the vehicle width direction of the nut plate when the impact load is applied.
