PROBLEM TO BE SOLVED: To heighten rigidity of a back panel having an opening.SOLUTION: In a vehicle body rear part structure 1 including a bulk head 10 for joining a frame-like back panel 20 having an opening 20x to a rear side member 30, a fixed position between the back panel 20 and the bulk head 10 corresponds to a starting point S0 where a bottom side 20x1 of the opening 20x of the back panel 20 is deformed to a curve R including a direction orthogonal to the bottom side 20x1.SELECTED DRAWING: Figure 4 |
