PROBLEM TO BE SOLVED: To effectively reinforce a damper supporting portion even if a recessed portion of a rear floor panel is expanded, and to effectively suppress the vertical displacement of the damper supporting portion and the falling inward of a rear wheel house.SOLUTION: A vehicle body rear part structure is provided with a first reinforcing structure 70 which extends in a vertical direction while inclining forward/backward along an in-vehicle side wall surface 40A of a rear wheel house 40, is joined with a damper supporting portion 46 at an upper end, and joint with the rear side frame 14 on a side right-and-left corresponding side at the same fore-and-aft direction position as a part near a joint portion of a first rear floor cross member 26 to a rear side frame 14 at a lower end; and a second reinforcing structure 90 which extends in a generally vertical direction along the in-vehicle side wall surface 40A of the rear wheel house 40 at the same fore-and-aft direction position as a generally center portion of the damper supporting portion 46, is joined with the damper supporting portion 46 at an upper end, and joined with the rear side frame 14 on a side right-and-left corresponding at the same fore-and-aft direction position as a part near the joint portion of a second rear cross member 28 to the rear side frame 14 at a lower end.SELECTED DRAWING: Figure 2 |
