To provide a vehicle body rear part structure which can inhibit weight increase to inhibit heat damage at a vehicle rear part.SOLUTION: A vehicle body rear part structure includes in a vehicle body of a vehicle rear part: a power generation unit 10 which is constituted of a power generator 11 for generating electric power for driving a vehicle 1 and an internal combustion engine 12 for power generation serving as a power source of the power generator 11; and an exhaust unit 20 which is constituted of an exhaust pipe 21 connected to the internal combustion engine 12 for power generation, an upstream catalyst 22, a downstream catalyst 23, and a muffler 24. The vehicle body rear part structure also includes: an enclosing member 40 which encloses the exhaust unit 20 from six sides; and a blower fan 50 which blows outer air to an interior of the enclosing member 40. The enclosing member 40 includes: a ventilation opening S2 into which the outer air is introduced through the blower fan 50; and a bottom part opening S1 which opens at a portion corresponding to an exhaust pipe outlet 21a of the exhaust pipe 21. The ventilation opening S2 of the enclosing member 40 is disposed opposite to the bottom part opening S1 of the enclosing member 40.SELECTED DRAWING: Figure 2
