The left and right triangular side core members 46A, 46A that are connected and tapered forward and tapered, and are tapered between the left and right side core members 46A, 46A and tapered rearward. Since it is formed of the central core member 46B of the shape (see FIG. 3), not only the collision load of the rear surface collision input to the rear end cross member 24 is directly dispersed from the rear end cross member 24 to the rear side frames 23 but To the left and right rear side frames 23, 23 through the triangular side core members 46A, 46A By distributing reached, it is possible to absorb the collision load of the rear-end collision efficiently in a simple structure and lightweight.
　特に、左右の側部コア材４６Ａ，４６Ａは、中央コア材４６Ｂとの境界線の方向に沿って延びる多数の凹凸部４６ａ…を有する波板からなるので、リヤエンドクロスメンバ２４に入力した後面衝突の衝突荷重を効率的にリヤサイドフレーム２３，２３に伝達して分散することができ、しかも中央コア材４６Ｂは車幅方向に延びる多数の凹凸部４６ｂ…を有する波板からなるので、中央コア材４６Ｂが筋交いとして機能することで、左右の側部コア材４６Ａ，４６Ａが車幅方向内側に変形するのを防止して前記衝突荷重を更に効率的にリヤサイドフレーム２３，２３に伝達することができる。 In particular, since the left and right side core members 46A, 46A are formed of a corrugated sheet having a large number of uneven portions 46a extending along the direction of the boundary line with the central core member 46B, the rear surface collision after entering into the rear end cross member 24 Collision load can be efficiently transmitted to the rear side frames 23, 23 and dispersed, and the central core member 46B is formed of a corrugated sheet having a large number of uneven portions 46b extending in the vehicle width direction. The 46B functions as a brace to prevent the left and right side core members 46A, 46A from being deformed inward in the vehicle width direction, and the collision load can be more efficiently transmitted to the rear side frames 23, 23. .
　このとき、左右の側部コア材４６Ａ，４６Ａの後端をリヤエンドクロスメンバ２４の内部に嵌入して該リヤエンドクロスメンバ２４の後壁に接続したので（図６および図８参照）、リヤエンドクロスメンバ２４に入力した後面衝突の衝突荷重を左右の側部コア材４６Ａ，４６Ａに一層確実に伝達することができる。 At this time, the rear ends of the left and right side core members 46A, 46A are inserted into the inside of the rear end cross member 24 and connected to the rear wall of the rear end cross member 24 (see FIGS. 6 and 8). The collision load of the rear surface collision input to 24 can be more reliably transmitted to the left and right side core members 46A, 46A.
　しかもキャビン１１はリヤサイドフレーム２３の前端から前下方に延びるサイドシル２２を備え、サイドシル２２の内部に水平方向に延びる後部第１連結板４９を配置し、後部第１連結板４９の後端をリヤサイドフレーム２３の後部仕切り部材５１の前端に接続するとともに、後部第１連結板４９の前端をサイドシル２２の上壁２２ｅに接続したので（図４参照）、リヤバンパービーム６０に入力した衝突荷重がリヤエンドクロスメンバ２４からリヤサイドフレーム２３を介してサイドシル２２に伝達されたとき、その衝突荷重をリヤサイドフレーム２３の後部仕切り部材５１から後部第１連結板４９を介してサイドシル２２に確実に伝達して吸収することができる。 In addition, the cabin 11 has a side sill 22 extending forward and downward from the front end of the rear side frame 23, and a rear first connecting plate 49 extending horizontally in the side sill 22 is disposed, the rear end of the rear first connecting plate 49 being a rear side frame Since the front end of the rear first connecting plate 49 is connected to the upper wall 22e of the side sill 22 while it is connected to the front end of the rear partition member 51 (see FIG. 4), the collision load input to the rear bumper beam 60 is the rear end cross When it is transmitted from the member 24 to the side sill 22 through the rear side frame 23, the collision load is reliably transmitted from the rear partition member 51 of the rear side frame 23 to the side sill 22 through the rear first connecting plate 49 and absorbed. Can.
　またリヤサイドフレーム２３の内部を後部仕切り部材５１によって上部空間２３ａおよび下部空間２３ｂに仕切ったので、後部切り板５１によりリヤサイドフレーム２３の剛性を確保して側面衝突の衝突荷重を確実に支持しながら、リヤサイドフレーム２３の高さを増加させて荷室の容積を拡大することができる。 Further, since the inside of the rear side frame 23 is divided into the upper space 23a and the lower space 23b by the rear partition member 51, the rigidity of the rear side frame 23 is secured by the rear cut plate 51 to securely support the collision load of the side collision, The height of the rear side frame 23 can be increased to increase the volume of the luggage compartment.
　またインナースキン１９におけるリヤサイドフレーム２３およびリヤフロアパネル２７の境界に第１傾斜面１９ｂを設けるとともに、アウタースキン２０におけるリヤサイドフレーム２３およびリヤフロアパネル２７の境界に第２傾斜面２０ｂを設け、リヤサイドフレーム２３の内部を上部空間２３ａおよび下部空間２３ｂに仕切る後部仕切り板５１の車幅方向内端を第１傾斜面１９ｂに接続したので（図７参照）、第１傾斜面１９ｂおよび第２傾斜面２０ｂの相乗効果で、リヤフロアパネル２７を介して分散された後面衝突の衝突荷重を確実に支持できるだけでなく、サイドシル２２に側面衝突の衝突荷重が入力したときに、その衝突荷重をリヤフロアパネル２７に効率的に伝達してサイドシル２２が車幅方向内方に倒れるのを防止することができる。 The first inclined surface 19 b is provided at the boundary between the rear side frame 23 and the rear floor panel 27 in the inner skin 19, and the second inclined surface 20 b is provided at the boundary between the rear side frame 23 and the rear floor panel 27 in the outer skin 20. Since the vehicle width direction inner end of the rear partition plate 51 that divides the inside into the upper space 23a and the lower space 23b is connected to the first inclined surface 19b (see FIG. 7), the synergy of the first inclined surface 19b and the second inclined surface 20b In addition to being able to reliably support the collision load of the rear surface collision dispersed via the rear floor panel 27 by the effect, when the collision load of the side collision is input to the side sill 22, the collision load is efficiently applied to the rear floor panel 27 Transmit to prevent the side sill 22 from falling inward in the vehicle width direction Door can be.
　また後部仕切り部材５１は、インナースキン１９およびアウタースキン２０の接合フランジ１９ａ，２０ａ間に挟持したフランジ部５１ａから下向きおよび車幅方向内向きにクランク状に屈曲する縦壁５１ｂおよび横壁５１ｂと、横壁５１ｂから斜めに延びてインナースキン１９の第１傾斜面１９ｂに接続する傾斜壁５１ｃとを備えるので（図７参照）、箱状部材６１を大型化することなく、その高さをリヤバンパービーム６０の高さに一致させることができるだけでなく、後部仕切り部材５１を第１傾斜面１９ｂに接続したことで、後部仕切り部材５１の車幅方向の幅Ｗ１をリヤサイドフレーム２３の車幅方向の幅Ｗ２よりも拡大し、リヤサイドフレーム２３の倒れ剛性を一層高めることができる。 Further, the rear partition member 51 includes a vertical wall 51b and a horizontal wall 51b which are bent in a crank shape downward and inward in the vehicle width direction from the flange portion 51a sandwiched between the bonding flanges 19a and 20a of the inner skin 19 and the outer skin 20; Since the sloped wall 51c obliquely extending from 51b and connected to the first sloped surface 19b of the inner skin 19 is provided (see FIG. 7), the height of the box-shaped member 61 can be increased without changing the size of the rear bumper beam 60. The width W1 of the rear partition member 51 in the vehicle width direction can be made equal to the width W2 of the rear side frame 23 in the vehicle width direction by connecting the rear partition member 51 to the first inclined surface 19b. It is possible to further enlarge the falling rigidity of the rear side frame 23 by enlarging it.
　また箱状部材６１の下面にアウタースキン２０を挟んで荷重受け部材６６を固定し、荷重受け部材６６の底面６６ａをリヤバンパービーム６０の下面よりも下方に突出させたので（図６～図８参照）、リヤバンパービーム６０よりも低い位置に入力する衝突荷重を荷重受け部材６６で受け止めてリヤバンパービーム６０およびリヤサイドフレーム２３に伝達することができる。しかも荷重受け部材６６をリヤサイドフレーム２３およびリヤエンドクロスメンバ２４に跨がるようにＬ字状に形成したので、リヤサイドフレーム２３およびリヤエンドクロスメンバ２４の接続部を効果的に補強することができる。 Further, the load receiving member 66 is fixed to the lower surface of the box-like member 61 with the outer skin 20 interposed therebetween, and the bottom surface 66a of the load receiving member 66 is protruded below the lower surface of the rear bumper beam 60 (see FIGS. 6 to 8). Reference load) The impact load input to a position lower than the rear bumper beam 60 can be received by the load receiving member 66 and transmitted to the rear bumper beam 60 and the rear side frame 23. Moreover, since the load receiving member 66 is formed in an L shape so as to straddle the rear side frame 23 and the rear end cross member 24, the connection portion of the rear side frame 23 and the rear end cross member 24 can be effectively reinforced.
　またロールバー１７の上部を一対のステー１８，１８を介してリヤサイドフレーム２３，２３に接続したので、ロールバー１７の倒れ剛性を大幅に高めることができる。このとき、平面視でステー１８，１８はロールバー１７に直交するので（図２参照）、ロールバー１７の前後方向への倒れをステー１８，１８によって確実に阻止することができる。またステー１８の下端を支持部材６７を介してリヤサイドフレーム２３に固定したので、ステー１８とリヤサイドフレーム２３とを強固に固定することができるだけでなく、この支持部材６７を利用してリヤサスペンション装置のダンパー７３の上端を支持したので（図１および図８参照）、支持部材６７を利用してロールバー１７のステー１８およびリヤサスペンション装置のダンパー７３の両方をリヤサイドフレーム２３に強固に支持することが可能となり、それらを別個にリヤサイドフレーム２３に支持する場合に比べて車体重量を軽減することができる。 Further, since the upper portion of the roll bar 17 is connected to the rear side frames 23, 23 through the pair of stays 18, 18, the falling rigidity of the roll bar 17 can be significantly enhanced. At this time, since the stays 18, 18 are orthogonal to the roll bar 17 in plan view (see FIG. 2), the stays 18, 18 can reliably prevent the roll bar 17 from falling in the front-rear direction. Further, since the lower end of the stay 18 is fixed to the rear side frame 23 through the support member 67, not only can the stay 18 and the rear side frame 23 be firmly fixed, but also using the support member 67 Since the upper end of the damper 73 is supported (see FIGS. 1 and 8), both the stay 18 of the roll bar 17 and the damper 73 of the rear suspension device can be firmly supported on the rear side frame 23 using the support member 67. This enables the vehicle weight to be reduced as compared with the case of separately supporting them on the rear side frame 23.
　特に、支持部材６７は、リヤサイドフレーム２３に固定される上壁６７ａおよび側壁６７ｂを有するＬ字状断面の部材であり、上壁６７ａにステー１８を固定し、側壁６７ｂから張り出したダンパー支持座６７ｃを前後の補強リブ６７ｄ，６７ｅで側壁６７ｂに接続したので（図６～図８参照）、支持部材６７に対するダンパー支持座６７ｃの剛性を高めてダンパー７３からダンパー支持座６７ｃに入力する荷重を確実に受け止めることができる。 In particular, the support member 67 is a member having an L-shaped cross section having an upper wall 67a and a side wall 67b fixed to the rear side frame 23, the stay 18 fixed to the upper wall 67a, and a damper support seat 67c protruding from the side wall 67b. Are connected to the side wall 67b by the front and rear reinforcement ribs 67d and 67e (see FIGS. 6 to 8), so the rigidity of the damper support seat 67c with respect to the support member 67 is increased to ensure the load input from the damper 73 to the damper support seat 67c Can be
　またリヤサイドフレーム２３は第１バルクヘッド６９および第２バルクヘッド７０を備え、支持部材６７は第１バルクヘッド６９および第２バルクヘッド７０間に位置するので、リヤサイドフレーム２３にステー１８が固定される部分の強度を第１、第２バルク６９，７０ヘッドにより高めることができる。しかも第１バルクヘッド６９および第２バルクヘッド７０は、支持部材６７を締結するボルト７２…が螺合するナット７１…を備えるので、支持部材６７を簡単かつに強固に固定することができる。更に、リヤサイドフレーム２３の内部を後部仕切り板５１によって上部空間２３ａおよび下部空間２３ｂに仕切り、上部空間２３ａ内に第１バルクヘッド６９および第２バルクヘッド７０を配置したので、強度を確保しながら第１、第２バルクヘッド６９，７０を必要最小限に小型化して軽量化を図ることができる。 Also, since the rear side frame 23 includes the first bulkhead 69 and the second bulkhead 70, and the support member 67 is located between the first bulkhead 69 and the second bulkhead 70, the stay 18 is fixed to the rear side frame 23. The strength of the portion can be enhanced by the first and second bulks 69 and 70 heads. Moreover, since the first bulkhead 69 and the second bulkhead 70 are provided with the nuts 71 engaged with the bolts 72 for fastening the support member 67, the support member 67 can be fixed easily and firmly. Furthermore, the inside of the rear side frame 23 is partitioned by the rear partition plate 51 into the upper space 23a and the lower space 23b, and the first bulkhead 69 and the second bulkhead 70 are disposed in the upper space 23a. The first and second bulkheads 69 and 70 can be downsized to the minimum necessary for weight reduction.
　更にまた、リヤサイドフレーム２３はロールバー１７の取付部近傍にキックアップ部２６のコア材４５を車幅方向外側に延長した第３バルクヘッド４５ｂを備え、第３バルクヘッド４５ｂを、リヤサイドフレーム２３の前端から前下方に延びるサイドシル２２の内部に配置した補強部材である前部仕切り部材４７、後部第１連結板４９、後部第２連結板５０、上部エネルギー吸収部材５２および下部エネルギー吸収部材５３に接続したので（図４および図５参照）、リヤサイドフレーム２３の断面形状が上下方向に高い場合であっても剛性を確保することができる。 Furthermore, the rear side frame 23 is provided with a third bulkhead 45b in the vicinity of the mounting portion of the roll bar 17 with the core member 45 of the kickup portion 26 extended outward in the vehicle width direction. Connected to the front partition member 47 which is a reinforcement member disposed inside the side sill 22 extending forward and downward from the front end, the rear first connecting plate 49, the rear second connecting plate 50, the upper energy absorbing member 52 and the lower energy absorbing member 53 Because of this (see FIGS. 4 and 5), rigidity can be secured even when the cross-sectional shape of the rear side frame 23 is high in the vertical direction.

It is supported by 101,101.
　次に、上記構成を備えた本発明の第２の実施の形態の作用を説明する。 Next, the operation of the second embodiment of the present invention having the above configuration will be described.
　キャビン１１のフロントフロアパネル２５の後端から起立するキックアップ部２６と、キックアップ部２６の上端から後方に延びるリヤフロアパネル２７との角部１０５（図１１参照）は急激に屈曲していて応力が集中し易いため、外部から曲げモーメントが入力しても折れ曲がらないように補強する必要がある。本実施の形態によれば、Ｌ字状をなす各々の燃料タンク支持ブラケット１０１の前縁をキックアップ部２６の後壁に第１ボルト１０６で締結し、上縁をリヤフロアパネル２７の下面に第２ボルト１０７，１０７で締結したので、角部１０５を挟むキックアップ部２６およびリヤフロアパネル２７と、燃料タンク支持ブラケット１０１の筋交い部１０１ｆとが三角形を構成することで、角部１０５を挟んでキックアップ部２６およびリヤフロアパネル２７が成す角度を筋交い部１０１により拘束し、角部１０５の折れ曲がりを効果的に抑制することができる。 The corner portion 105 (see FIG. 11) between the kickup portion 26 standing up from the rear end of the front floor panel 25 of the cabin 11 and the rear floor panel 27 extending rearward from the upper end of the kickup portion 26 is sharply bent and stressed. Since it is easy to concentrate, it is necessary to reinforce so that it will not bend even if a bending moment is input from the outside. According to the present embodiment, the front edge of each L-shaped fuel tank support bracket 101 is fastened to the rear wall of the kickup portion 26 with the first bolt 106, and the upper edge is fixed to the lower surface of the rear floor panel 27. Since the two bolts 107 and 107 are fastened, the kick-up portion 26 and the rear floor panel 27 sandwiching the corner portion 105 and the bracing portion 101 f of the fuel tank support bracket 101 form a triangle, thereby sandwiching the corner portion 105 The angle formed by the up portion 26 and the rear floor panel 27 can be restrained by the bracing portion 101, and bending of the corner portion 105 can be effectively suppressed.
　特に、筋交い部１０１ｆの前端近傍はキックアップ部２６のコア材４５に埋設した強固な第１インサート部材１０３に第１ボルト１０６で固定され、筋交い部１０１ｆの後端近傍はリヤフロアパネル２７のコア材４６に埋設した強固な第２インサート部材１０４に第２ボルト１０７で固定されるので、筋交い部１０１ｆの両端をキックアップ部２６およびリヤフロアパネル２７に強固に結合して補強効果を高めることができる。また燃料タンク１００をキャビン１１の下面に支持するための燃料タンク支持ブラケット１０１，１０１を利用してキックアップ部２６およびリヤフロアパネル２７の角部１０５を補強するので、特別の補強部材が不要になって部品点数、重量およびコストを削減することができる。また燃料タンク支持ブラケット１０１の一部を斜めに切除して筋交い部１０１ｆを形成したので、燃料タンク支持ブラケット１０１の重量を削減することができる。 In particular, the vicinity of the front end of the bracing portion 101f is fixed to the strong first insert member 103 embedded in the core member 45 of the kickup portion 26 by the first bolt 106, and the core material of the rear floor panel 27 is fixed near the rear end of the bracing portion 101f. Since it is fixed to the strong second insert member 104 embedded in 46 by the second bolt 107, both ends of the brace portion 101f can be firmly connected to the kickup portion 26 and the rear floor panel 27 to enhance the reinforcing effect. Further, since the kick-up portion 26 and the corner portion 105 of the rear floor panel 27 are reinforced using the fuel tank support brackets 101 and 101 for supporting the fuel tank 100 on the lower surface of the cabin 11, a special reinforcing member is not necessary.
