A battery unit which stores plural battery modules therein is attached to respective lower faces of a pair of floor frames at its both sides. The battery unit comprises an attaching bracket which protrudes substantially horizontally from the battery case and is positioned just below the lower face of the floor frame with a distance therebetween. A specified rigidity ratio is set for an attachment portion of the battery unit to the floor frame, and the attaching bracket is attached to the lower face of the floor frame via an intermediate part such that the above-described rigidity ratio is 0.1 or greater.
