PROBLEM TO BE SOLVED: To further relax stress concentration and further increase the strength and rigidity of a closed-cross-sectional part, when a torsional load of the closed-cross-sectional part is applied in a partition portion of a sedan-type vehicle body rear part.SOLUTION: In a structure of a closed-cross-sectional part of a sedan type vehicle body rear part, a reinforcement member 8 is joined to an overlapping part 9 of a partition front door panel 3 and a partition side member 2, which form part of the closed-cross-sectional part 7. The reinforcement member 8 is arranged in a part where the partition side complete 18 including a partition side member 2 is joined to a partition panel complete 6 including a partition front panel 4 forming the closed-cross-sectional part 7 by covering the partition front panel 3.

    【課題】セダンタイプの自動車の車体後部のパーティション部分における閉断面形状部の捩り負荷時の応力集中の緩和や閉断面形状部の強度・剛性のアップを促進させる。【解決手段】セダンタイプの自動車の車体後部の閉断面形状部の構造で、閉断面形状部7の一部を成すパーティションフロントロアパネル3とパーティションサイドメンバ2との重なり部9に補強部材8を接合した。パーティションサイドメンバ2を含むパーティションサイドコンプリート18と、パーティションフロントロアパネル3を覆って閉断面形状部7を成すパーティションフロントパネル4を含むパーティションパネルコンプリート6と、の接合部に前記補強部材8を配置した。【選択図】図1
