VEHICLE BODY SIDE STRUCTURE

A vehicle body side structure includes a lid openably and closably attached to a side surface of a vehicle body rear part, and a quarter window provided at a position rearward of a rear door opening. A gap extending in a front-rear direction of a vehicle body is formed by an upper side of the lid extending in the front-rear direction of the vehicle body and a lower side of the quarter window extending in the front-rear direction of the vehicle body.
