A vehicle front structure includes side frames in pairs, a bumper beam, lower frames in pairs, and a lower beam. The lower beam extends in a vehicle width direction on a vehicle lower side of the bumper beam. The lower beam is coupled to vehicle-front-side end parts of the lower frames. The lower beam includes a front lower beam member and lower beam members in pairs. The front lower beam member constitutes a vehicle-front-side part of the lower beam. The front lower beam member extends in the vehicle width direction. Longitudinal-direction end parts of the front lower beam member are disposed outward in the vehicle width direction, as seen from the lower frames. The rear lower beam members constitute a vehicle-rear-side part of the lower beam. The rear lower beam members are joined respectively to both of the longitudinal-direction end parts of the front lower beam member.

A battery cooling air discharge structure is configured to suppress noise of the cooling air for a battery. The battery cooling air discharge structure includes a floor panel, a floor, a plurality of rows of seats and an exhaust duct. The floor panel bottom forms a lower part of a vehicle body of a vehicle and enables placement of a battery. The floor panel top portion is arranged above the floor panel to allow placement of the battery between the floor panel top portion and the floor panel. The seats are arranged on the floor. The exhaust duct discharges battery cooling air. The exhaust duct has an exhaust port located between the floor and a seating part of a rear seat that constitutes the seats. An underside of the seating part has a notch. At least an area of the exhaust port is located adjacent to the notch.

A vehicle rear portion structure includes a cross member that extends in a vehicle width direction at a vehicle rear, a rear wheel house that accommodates a rear tire, a rear pillar that extends in a vehicle vertical direction, a reinforcing member that connects the rear pillar with the rear wheel house, and a joining member that connects a lower end portion of the reinforcing member with one end portion of the cross member. The rear pillar is divided into a general portion and a high-rigidity portion. The high-rigidity portion is connected to an upper end portion of the general portion and is specified with a higher rigidity than the general portion. The reinforcing member is connected to the high-rigidity portion.

On both sides under a floor of an electric vehicle, side members are provided, each in a closed cross sectional shape. Collars and the like are provided in the side members. On a lower side of a lower wall of each of the side members, cross members which are fixed by using the collars or the like are provided. Between the side members on both sides, a main battery is provided and supported by the cross members. In the vicinity of a lower side of a doorway of the electric vehicle, a cutout part is formed such that a height of a portion of an upper wall of the side member is relatively lowered. On an upper surface of the cutout part, a reinforcing member is provided. A ramp passes through a space on an upper side of the cutout part.
