Therefore, the load can be distributed by fixing at three points, and the three fixing points P1, P2, and P3 are arranged compactly. These three fixed points P1, P2, and P3 are directly connected to the bracket 10 and the three reinforcing members (upper rail 30, front reinforcement 40, and rear reinforcement 50), so the connecting fixed portion A The overall rigidity can be increased.
- the three fixed points P1, P2, and P3 are three-dimensionally arranged offset in the longitudinal direction, vertical direction, and vehicle width direction, so that they can cope with external forces in all directions. This can enhance the dispersion function and improve the effect of suppressing deformation.
- the connecting portion 13 of the bracket 10 has ridgelines 71 to 78 formed by bending the bracket 10 in the thickness direction. This improves the rigidity of the bracket 10.
- the connecting portion 13 of the bracket 10 has a structure in which the first to fifth sloped portions 21 to 25 are provided, but the number of sloped portions is not limited to this.
- the angle of inclination, shape, etc. of each inclined portion are not limited to those shown in the drawings.

一対のサイドゲート3,3は、ヘッダーボード2に交差して配置される。具体的には、一対のサイドゲート3,3は、ヘッダーボード2の左右両端部に接続され、主に車両後方に延びて、車両荷箱1の左右両側の壁面を構成する。それぞれのサイドゲート3の下端部には、ホイールアーチ3aが形成される。
テールゲート4は、一対のサイドゲート3,3の後方端部に接続され、左右方向に延びる。
フロアパネル5は、ヘッダーボード2と、一対のサイドゲート3,3と、テールゲート4と、で囲まれた空間の下方側を閉じる。
第2傾斜部22は、第2接続部15の中央に位置する。
第3傾斜部23は、第2傾斜部22の前方に位置する。
第4傾斜部24は、第2傾斜部22の後方に位置する。
第5傾斜部25は、第2接続部15の下部に位置し、第2固定部分12の上端と接続する。
第2稜線72は、第1稜線71と接続し、前方に向かうにしたがって上方且つ車幅方向内側に延びる。第2稜線72は、第1傾斜部21と第3傾斜部23とを区画する。
第3稜線73は、第1稜線71と接続し、後方に向かうにしたがって上方且つ車幅方向内側に延びる。第3稜線73は、第1傾斜部21と第4傾斜部24とを区画する。
第4稜線74は、第1稜線71及び第2稜線72と接続し、下方に向かうにしたがって車幅方向外側に延びる。第4稜線74は、第2傾斜部22と第3傾斜部23とを区画する。
第5稜線75は、第1稜線71及び第3稜線73と接続し、下方に向かうにしたがって車幅方向外側に延びる。第5稜線75は、第4稜線74と略平行である。第5稜線75は、第2傾斜部22と第4傾斜部24とを区画する。
第6稜線76は、車両前後方向に略平行に延び、第2傾斜部22と第5傾斜部25とを区画する。第6稜線76は、第1稜線71と略平行である。
第7稜線77は、第4稜線74及び第6稜線76と接続し、前方に向かうにしたがって下方且つ車幅方向外側に延びる。第7稜線77は、第3傾斜部23と第5傾斜部25とを区画する。
第8稜線78は、第5稜線75及び第6稜線76と接続し、後方に向かうにしたがって下方且つ車幅方向外側に延びる。第8稜線78は、第4傾斜部24と第5傾斜部25とを区画する。
特に、本実施形態のブラケット10は、ブラケット10の一方側に設けられ、ヘッダーボード2の上部(アッパーレール30)に固定される第1固定部分11と、ブラケット10の他方側に設けられ、ヘッダーボード2よりも車両前方に位置するサイドゲート3の所定箇所(前側リンフォース40)に固定される第2固定部分12と、を有する。すなわち、ブラケット10の第1固定部分11と第2固定部分12とが車両前後方向にオフセットしている。したがって、第1固定部分11及び第2固定部分12において、外力の一部を剪断力として受けることができ、ブラケット10への負荷を軽減することができる。
また、第2固定部分12がヘッダーボード2よりも車両前方に位置するので、ブラケット10は車両荷箱1の収容領域外に位置され、車両荷箱1の収容容積を大きくできる。
また、ブラケット10が板状であることで、軽量化ができる。
また、接続部13で接続された第1固定部分11と第2固定部分12は、車両前後方向のオフセットに加え、車両上下方向及び車幅方向にもオフセットするので、第1固定部分11(第1固定点P1)と第2固定部分12(第2固定点P2)との位置関係が三次元となる。したがって、第1固定部分11(第1固定点P1)と第2固定部分12(第2固定点P2)に生じる応力は、前後方向、上下方向、車幅方向に分散し易くなる。この結果、ブラケット10の応力分散の機能がより高まり、変形防止効果を高めることができる。
特に、図13で示したように、アッパーレール30の延在部30bに浮き上がるような変形を生じさせる力F3が作用する場合に、ブラケット10への負荷を軽減することができる。仮に、第1固定点P1と第2固定点P2とが、車両前後方向に同一位置である場合、第1固定点P1と第2固定点P2とを結んだ線と、車両後方に向かう力F3と、が垂直になってしまい、効率良く負荷を受けることが困難である。
