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

    【課題】重量増加を抑えて、車両後部における熱害を抑制できる車体後部構造を提供することを目的とする。【解決手段】車両1の走行用電力を発電する発電機11、及び発電機11の動力源である発電用内燃機関12で構成された発電ユニット10と、発電用内燃機関12に接続された排気管21、上流触媒22、下流触媒23、及び消音器24で構成された排気ユニット20とを、車両後部の車体に備えた車体後部構造であって、排気ユニット20の六方を囲繞する囲い部材40と、囲い部材40の内部に外気を送風する送風ファン50とを備え、囲い部材40が、送風ファン50を介して外気が導入される送風開口S2と、排気管21の排気管出口21aに対応する部分を開口した底部開口S1とを備え、囲い部材40の送風開口S2が、囲い部材40の底部開口S1に対して対向配置されたことを特徴とする。【選択図】図2
