VEHICLE REAR-SIDE STRUCTURE

A vehicle rear-side structure is configured to ease an impact applied onto a battery pack of a vehicle upon an occurrence of a collision. The vehicle rear-side structure includes side frames and a rear-end-collision impact reducer. The side frames extend in a front-rear direction of the vehicle and are disposed at positions at which the side frames sandwich the battery pack therebetween in a widthwise direction of the vehicle. The rear-end-collision impact reducer is disposed between and above the side frames at a rear side of the battery pack. The rear-end-collision impact reducer is configured to allow air, which is to be sent to a battery stack included in the battery pack, to flow through the rear-end-collision impact reducer.
