A vehicle rear structure includes a battery outer case, a side frame provided in a side portion of the battery outer case and extending forward from a rear side of the battery outer case, a rear vehicle frame member provided behind the battery outer case and inwardly from an end of a vehicle body so as to extend in the vehicle front-rear direction, and a front vehicle frame member provided in front of the battery outer case so as to extend in the vehicle front-rear direction and being connected to a front end portion of the side frame. The rear vehicle frame member is connected to a rear end portion of the side frame.

Vehicle rear structure

A bumper reinforcement mounting structure includes a plurality of vehicle body skeleton members disposed at an interval in a vehicle width direction and extending in a vehicle front-rear direction, a bumper reinforcement that extends in the vehicle width direction and is mounted on the vehicle body skeleton members, and a first mounting member that is used to mount a mounting portion of the bumper reinforcement on one of the vehicle body skeleton members. The first mounting member has shear strength that is lower than shear strength of the mounting portion of the bumper reinforcement.

Bumper reinforcement mounting structure

An impact absorbing portion and a bumper reinforcement are formed in one piece, so an intermediate member for connecting the impact absorbing portion to the bumper reinforcement is no longer necessary. Therefore, the generation of stress concentration is able to be inhibited. As a result, load transmission efficiency with which a load is transmitted from the bumper reinforcement to the impact absorbing portion is able to be improved.

Vehicle bumper

A vehicle lower portion structure has: a tunnel portion disposed at a vehicle transverse direction central portion of a floor portion; a front side member whose rear portion is disposed at a vehicle lower side of the floor portion and a vehicle transverse direction outer side of the tunnel portion; a first member including a first horizontal wall that extends from the rear portion toward a vehicle transverse direction inner side, and a first vertical wall bent toward a vehicle upper side from the first horizontal wall; and a second member spanning an opening portion of the tunnel portion. The second member includes a second horizontal wall, and a second vertical wall that is bent toward the vehicle upper side from the second horizontal wall, is disposed parallel to the first vertical wall, and is joined to the first vertical wall.

Vehicle lower portion structure

There is provided a vehicle lower section structure including a rocker that extends in a vehicle front-rear direction at a vehicle width direction outer side, a tunnel section that extends in the vehicle front-rear direction at a central portion in the vehicle width direction, a pair of dash cross members that extend in the vehicle width direction at a lower side of a dash panel, that are separated by the tunnel section, tunnel reinforcement that is disposed at a lower side in the vehicle up-down direction that extends in the vehicle front-rear direction, wherein a first front flange is formed at a front end of the dash cross member in the vehicle front-rear direction, and wherein a second front flange is disposed at a position opposing the first front flange across the dash panel or a floor section.

Vehicle lower section structure

A vehicle body end section structure is obtained that enables a spacer member that transmits load to a framework member in a small overlap collision to be suppressed from impinging on a wheel in a minor collision. The vehicle body end section structure comprises a pair of left and right framework members, a bumper framework section connected to leading end portions of the pair of framework members, and a spacer member that projects out from a jutting-out portion of the bumper framework section toward a framework member side. The spacer member is disposed such that a rotation trajectory of the spacer member about a connection location between the bumper framework section and the framework member, the connection location is positioned on an opposite side in the vehicle width direction of the spacer member, does not impinge on a wheel in plan view.

Vehicle body end section structure

A vehicle lower portion structure has: a tunnel portion disposed at a vehicle transverse direction central portion of a floor portion; a front side member whose rear portion is disposed at a vehicle lower side of the floor portion and a vehicle transverse direction outer side of the tunnel portion; a first member including a first horizontal wall that extends from the rear portion toward a vehicle transverse direction inner side, and a first vertical wall bent toward a vehicle upper side from the first horizontal wall; and a second member spanning an opening portion of the tunnel portion. The second member includes a second horizontal wall joined to the first horizontal wall, and a second vertical wall that is bent toward the vehicle upper side from the second horizontal wall, is disposed parallel to the first vertical wall, and is joined to the first vertical wall.

A vehicle body lower structure includes: a floor connected to a dashboard panel, extending toward the vehicle rear side; a tunnel provided at a vehicle width direction center portion extending from the dashboard panel through the floor in the vehicle front-rear direction; a dashboard cross member joined to the dashboard panel, spanning in the vehicle width direction between a front end of the tunnel and a vehicle side section; and an under floor brace provided to a front end portion of the tunnel, extending in the vehicle width direction at the opposite side to the cabin, including both ends extending further toward the vehicle width direction outside than the front end portion of the tunnel and are fixed to the dashboard panel, the ends being located in positions facing vehicle width direction inside ends of the dashboard cross member via the dashboard panel.
