A lower structure of a vehicle body rear part includes a spare tire housing formed on a rear floor, a rear cross member disposed in front of the spare tire housing to connect side frames, and a hook reinforcing member extending in the vehicle longitudinal direction. The side frame at the vehicle rear of the rear cross member is divided into a frame front part and a frame rear part in the vehicle longitudinal direction, and the hook reinforcing member is divided into a reinforcing member front part and a reinforcing member rear part in the vehicle longitudinal direction. The lower structure is configured so that when a load F is applied from the vehicle rear to a vehicle body rear part, the side frame is deformed so as to be bent in an upward convex shape at a division position of the frame front part and the frame rear part, and also the rear floor and the hook reinforcing member are deformed so as to be bent in a downward convex shape at a division position of the reinforcing member front part and the reinforcing member rear part. |
