Thus, the power pack 106 can be attached to the attachment portions 118a and 118b with high attachment rigidity.

図４は、図１（ａ）のＡ−Ａ断面図である。図４に例示するように、本実施形態では、設置部１１６ａ、１１６ｂおよび取付部１１８ａ、１１８ｂの車両前後方向の位置を近づけることができるため、パワーパック１０６をよりリアシート１０４側、すなわち車両前方側に配置可能になっている。そのため、パワーパック１０６の車両後方側に空間を確保し、車体の後端１４４から距離Ｄ１を空けてパワーパック１０６を配置可能になっている。これによって、後突時におけるパワーパック１０６の損傷を事前に回避できる。   4 is a cross-sectional view taken along the line AA in FIG. As illustrated in FIG. 4, in the present embodiment, the positions of the installation portions 116 a and 116 b and the attachment portions 118 a and 118 b in the vehicle front-rear direction can be made closer, so that the power pack 106 can be closer to the rear seat 104 side, that is, the vehicle front side. Can be placed in. Therefore, a space is secured on the vehicle rear side of the power pack 106, and the power pack 106 can be disposed at a distance D1 from the rear end 144 of the vehicle body. Thereby, damage to the power pack 106 at the time of rear collision can be avoided in advance.

本実施形態によれば、リアシート１０４を車載部材側、すなわち車両後方側に配置することも可能である。例えば、リアシート１０４付近の室内空間をより広く確保することが可能である。このように、当該車両リアフロア構造１００では、空間がより有効に利用可能になっている。   According to this embodiment, it is also possible to arrange the rear seat 104 on the vehicle-mounted member side, that is, the vehicle rear side. For example, a wider indoor space near the rear seat 104 can be secured. Thus, in the vehicle rear floor structure 100, the space can be used more effectively.

再び図２を参照する。当該車両リアフロア構造１００では、各所の剛性向上も図っている。取付部１１８ａ、１１８ｂを有するブラケット１３６には、側部フランジ１４６が設けられている。側部フランジ１４６は、膨出部１２２ａの車幅方向の側部１２３に接合されている。側部フランジ１４６は、車両前後方向の荷重を、その接合のせん断方向に受ける。したがって、側部フランジ１４６を含んで設置されたブラケット１３６は、パワーパック１０６に対してより高い取付剛性を発揮できる。なお、側部フランジ１４６はさらに複数設けることができる。   Refer to FIG. 2 again. In the vehicle rear floor structure 100, the rigidity of each part is also improved. A side flange 146 is provided on the bracket 136 having the mounting portions 118a and 118b. The side flange 146 is joined to the side portion 123 of the bulging portion 122a in the vehicle width direction. The side flange 146 receives a load in the longitudinal direction of the vehicle in the shear direction of the joint. Therefore, the bracket 136 installed including the side flange 146 can exhibit higher mounting rigidity with respect to the power pack 106. A plurality of side flanges 146 can be provided.

図５は、図２のブラケット１３６のＢ−Ｂ断面図である。Ｂ−Ｂ断面図は、車両前後方向および車両上下方向に切断した断面である。ブラケット１３６は、前壁１１４との間に車幅方向にわたって閉断面Ｅ１を形成して接合されている。この構成によっても、ブラケット１３６の取付剛性はさらに高められている。   5 is a cross-sectional view of the bracket 136 shown in FIG. The BB cross-sectional view is a cross section cut in the vehicle longitudinal direction and the vehicle vertical direction. The bracket 136 is joined to the front wall 114 so as to form a closed section E1 over the vehicle width direction. Also with this configuration, the mounting rigidity of the bracket 136 is further increased.

シート取付パネル１３４の車両下方であって、リアフロアパネル１０２の前部領域１０８の下面には、クロスメンバ１４８が設けられている。クロスメンバ１４８は、前部領域１０８との間に閉断面Ｅ２を形成し、さらに前部領域１０８を介してシート取付パネル１３４に接続されている。   A cross member 148 is provided below the seat mounting panel 134 and on the lower surface of the front region 108 of the rear floor panel 102. The cross member 148 forms a closed cross section E2 with the front region 108, and is further connected to the seat mounting panel 134 through the front region 108.

図６は、図５の矢視Ｃに対応する車両リアフロア構造１００の斜視図である。クロスメンバ１４８は、収容部１１２の車両前側に沿って、車幅方向に延びている。このクロスメンバ１４８によって、シート取付パネル１３４の取付剛性、ひいてはシートレール１１０の取付剛性の向上が図られている。   FIG. 6 is a perspective view of the vehicle rear floor structure 100 corresponding to the arrow C in FIG. The cross member 148 extends in the vehicle width direction along the vehicle front side of the housing portion 112. The cross member 148 improves the mounting rigidity of the seat mounting panel 134 and, consequently, the mounting rigidity of the seat rail 110.

クロスメンバ１４８と、収容部１１２とには、リアフロアアウタリンフォース１５０がかけ渡されて設置されている。リアフロアアウタリンフォース１５０は、リアフロアパネル１０２（図４参照）、リアフロアインナリンフォース１３０、シートレールリンフォース１３２にボルト類によって共締めされていて、これら収容部１１２付近のさらなる剛性向上を図っている。その際のボルト類による共締めは、室内側では、ブラケット１３６の閉断面Ｅ１の内部によって行われていて、ボルトヘッド等が外部に露出しない構成となっている。   A rear floor outer ring force 150 is installed over the cross member 148 and the accommodating portion 112. The rear floor outer force 150 is fastened with bolts to the rear floor panel 102 (see FIG. 4), the rear floor inner force 130, and the seat rail reinforcement 132 to further improve the rigidity in the vicinity of the housing portion 112. . The fastening with bolts at that time is performed inside the closed section E1 of the bracket 136 on the indoor side, and the bolt head or the like is not exposed to the outside.
