Abstract: A front vehicle-body structure includes a front wheel including a wheel; and a side sill that extends in a front-rear direction on a rear side of the front wheel and has side sill inner and outer portions positioned on vehicle-width-direction inner and outer sides, respectively. Vehicle-width-direction end portions of the inner and outer portions are joined at a joined portion formed by the vehicle-width-direction end portions abutting against each other. The inner portion has a higher buckling strength in the front-rear direction than the outer portion. The joined portion has a second joined portion extending inclined to the vehicle-width-direction outer side toward a rear side, and a first joined portion bent from the second joined portion, extending to a front side, and positioned on a front-end portion of the side sill closer to the vehicle-width-direction inner side than a center line of the wheel in the vehicle width direction.

Abstract: A lower vehicle-body structure of a vehicle may include: a floor panel; a side sill; and a frame member that extends in the front-rear direction on the vehicle-width-direction inner side of the side sill and includes a front-rear extended portion that is in abutment against the side sill on the vehicle-width-direction inner side and extends in the vehicle front-rear direction along the side sill. The front-rear extended portion may include: a bottom face portion; an inner wall portion; and an inner-side flange that extends to the vehicle-width-direction inner side from a distal end portion of the inner wall portion and is joined to the floor panel. Deformation facilitating facilitators that facilitate deformation of the bottom face portion in the vehicle width direction when a collision load in the vehicle width direction is input may be formed in the bottom face portion.

Abstract: A lower vehicle-body structure allows miniaturization of an undercover and prevents an increase in minimum ground clearance. In the lower vehicle-body structure, a vehicle body floor includes step-up portions connected to a floor tunnel on opposite sides of the floor tunnel in a vehicle width direction at least in regions where first and second cross members are disposed on the vehicle body floor. The lower vehicle-body structure includes a mount member that faces the floor tunnel and connects the step-up portions on the opposite sides of the floor tunnel, and includes first and second undercovers that cover a lower side of the mount member so as to be continuous with a bottom surface of the vehicle body floor on outer sides of the step-up portions in the vehicle width direction.

Abstract: 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.
