A floor center member extends through a central part of a body floor of a vehicle and along a longitudinal direction of the vehicle, and a first floor cross member penetrates the floor center member to extend in a lateral direction of the vehicle. A reinforcing member extending in the longitudinal direction of the vehicle is disposed on the interior of the floor center member and above the first floor cross member.

Underbody structure of vehicle

A floor center member extends through a central part of a body floor of a vehicle and a longitudinal direction of the vehicle, and a first floor cross member penetrates the floor center member to extend in a lateral direction of the vehicle. The floor center member includes a coupling flange counter to a top wall of the first floor cross member. The coupling flange is coupled to the first floor cross member, by a bolt and a nut.

A battery unit is positioned under the floor of a vehicle chamber. A battery-side extension is provided on the lower surface of the front part of the battery unit case. A member-side extension member is provided, on the rear part of a suspension member, at a position facing the battery-side extension in the vehicle front-and-rear direction.

Vehicle front-part structure

A suspension member is mounted on the side members of an underbody. On the rear portion of the suspension member, spacers are provided between the suspension member and the underbody. Each spacer includes a bracket. The front end surface of the bracket is opposed to the rear wall surface of a main suspension body. During a frontal collision, the rear wall surface of the suspension member abuts against the bracket, whereby retreat of the suspension member is reduced.

Lower structure of vehicle

A vehicle front portion structure includes a pair of front side members arranged at a distance from each other in a vehicle width direction, each of the front side members extending in a vehicle front-rear direction, a gusset attached to a vehicle width direction outside surface of each of the front side members, protruding outwards in the vehicle width direction beyond the front side member, and having a vehicle width direction dimension decreasing toward a rear of a vehicle, and an MC cross member stretching between the front side members, in which the MC cross member and the front side member face each other in a state where the MC cross member and the front side member are apart from each other in the vehicle width direction at the same vehicle front-rear direction position as a rear end of the gusset.

Vehicle front portion structure

A vehicle body front portion structure includes a front pillar, a dash portion and a load transmission portion. The dash portion includes a dash panel. The load transmission portion includes a dash side structure portion that is fixed to a surface facing he vehicle rear side of a vehicle width direction outer side region of the dash portion, a pillar side structure portion that is fixed to a surface facing the vehicle width direction outer side of the pillar inner panel, and an intermediate structure portion that is connected to at least one of the dash side structure portion or the pillar side structure portion. The intermediate structure portion penetrates a hole portion and is set at a location at which a load that acts on the dash side structure portion when there is a frontal collision is transmitted to the pillar side structure portion.
