A vehicle-body lower structure includes: a front suspension member, a lower arm supported by the front suspension member; and a battery case that is disposed on the rear side of the front suspension member and houses a battery. The battery case includes: a front plate; and a frame extending in the left-right direction on a lower portion of the front plate. A block is attached to a front portion of the frame so as to be positioned on the rear side of the lower arm.

Vehicle-body lower structure

A vehicle rear structure protects a battery unit in a rear-end collision. The vehicle rear structure has a battery unit positioned behind a torsion beam; first and second cross members spanning between side members; a frame member that supports the battery unit; a bridge member spanning from the first cross member to the second cross member, and connected at a rear flange to the second cross member; and reinforcements that are respectively disposed to the side members and reinforce the side members from the front edge to the rear edge of the second cross member. The torsion beam is positioned near directly below the second cross member. The side members slope down to the front from the front end part of the reinforcement.
