特開２０１６−６８６０３号JP 2016-68603

しかしながら、従来の車両下部構造では、車両の側方からの荷重入力によって、フロア開口部の周縁が変形すると、フロア下方に配置されたバッテリや燃料タンク等の部品に、変形したフロアパネルが干渉してしまう虞があった。
本発明は、フロア開口部の周縁の変形を制御してフロア下方に配置された部品への干渉を抑制する車両下部構造を提供することを目的とする。 However, in the conventional vehicle lower structure, when the peripheral edge of the floor opening is deformed by the load input from the side of the vehicle, the deformed floor panel interferes with parts such as a battery and a fuel tank arranged under the floor. There was a risk that it would end up.
An object of the present invention is to provide a vehicle lower structure that controls deformation of the peripheral edge of a floor opening to suppress interference with parts arranged below the floor.

本発明は、下側に部品が配置されたフロアパネルと、フロアパネルのうち、部品の上方位置に開口形成されるフロア開口部と、フロア開口部の車幅方向で側方に、車体前後に延び下方へ凹設される凹溝部と、凹溝部とフロア開口部との間に配置されてフロア開口部の周縁を車両前後方向に補強する高剛性部とを備えることを特徴とする。 In the present invention, the floor panel in which the parts are arranged on the lower side, the floor opening formed in the upper position of the parts among the floor panels, and the floor opening laterally in the vehicle width direction, in the front and rear of the vehicle body. It is characterized by including a concave groove portion extending downwardly and recessed, and a highly rigid portion arranged between the concave groove portion and the floor opening to reinforce the peripheral edge of the floor opening in the front-rear direction of the vehicle.

以下、本発明の一実施形態について、適宜図面を参照しながら説明する。同一の構成要素には同一の符号を付し、重複する説明を省略する。方向を説明する際には、特に示さない限り、基本的に運転者から見た前後，左右あるいは上下に基づいて説明する。また、「車幅方向」は「左右方向」と同義である。
まず、車両１のフロアパネル２周辺の構成について説明する。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings as appropriate. The same components are designated by the same reference numerals, and duplicate description will be omitted. When explaining the direction, unless otherwise specified, the explanation is basically based on the front-back, left-right, or up-down as seen from the driver. In addition, "vehicle width direction" is synonymous with "left-right direction".
First, the configuration around the floor panel 2 of the vehicle 1 will be described.

図１は、本発明の実施形態の下部構造が適用される車両１で、車室内のフロアカーペットを外してフロアパネル２の上面を見た斜視図である。
フロアパネル２の左，右両側には、サイドシル３，３が設けられている。サイドシル３，３は、車両前後方向に延設されて車幅方向断面を略ロ字状の中空としている。そして、フロアパネル２の各測縁は、サイドシル３に接合されている。 FIG. 1 is a perspective view of a vehicle 1 to which the substructure of the embodiment of the present invention is applied, in which the floor carpet in the vehicle interior is removed and the upper surface of the floor panel 2 is viewed.
Side sills 3 and 3 are provided on both the left and right sides of the floor panel 2. The side sills 3 and 3 are extended in the front-rear direction of the vehicle and have a substantially square-shaped hollow cross section in the vehicle width direction. Then, each measuring edge of the floor panel 2 is joined to the side sill 3.

また、フロアパネル２の下側の一部には、部品としての燃料タンク４が配置されている。燃料タンク４は、主に、燃料を貯留するタンク本体と、タンク本体の上部に装着されるポンプユニット６とを有して構成されている。このうち、ポンプユニット６は、タンク本体から燃料を汲上げて、燃料パイプを介してエンジンへ供給する。 Further, a fuel tank 4 as a component is arranged in a part of the lower side of the floor panel 2. The fuel tank 4 is mainly composed of a tank body for storing fuel and a pump unit 6 mounted on the upper part of the tank body. Of these, the pump unit 6 pumps fuel from the tank body and supplies it to the engine via a fuel pipe.

フロアパネル２のうち、燃料タンク４の上方位置には、フロア開口部５が開口形成されている。フロア開口部５は、平面視略円形で略同径の円形の蓋体７により開閉可能となるように覆われている。
そして、フロア開口部５の位置に対応して、ポンプユニット６を動作させる各機器が配置されている。本実施形態のポンプユニット６は、フロア開口部５の周縁部５ａと車両上下方向でほぼ同じ高さ位置となるように配置されている（図３参照）。 A floor opening 5 is formed above the fuel tank 4 in the floor panel 2. The floor opening 5 is covered with a circular lid 7 which is substantially circular in plan view and has substantially the same diameter so as to be openable and closable.
Then, each device for operating the pump unit 6 is arranged corresponding to the position of the floor opening 5. The pump unit 6 of the present embodiment is arranged so as to be substantially at the same height position as the peripheral edge portion 5a of the floor opening 5 in the vertical direction of the vehicle (see FIG. 3).

このため、車室８内側からメンテナンスを行う際には、フロアカーペットおよび蓋体７を取外す。これにより、点検を行う者はフロア開口部５を介して直接、ポンプユニット６の点検およびポンプ等の機器の交換や修理が可能である。 Therefore, when performing maintenance from the inside of the vehicle interior 8, the floor carpet and the lid 7 are removed. As a result, the person performing the inspection can directly inspect the pump unit 6 and replace or repair the equipment such as the pump directly through the floor opening 5.

また、フロアパネル２には、凹溝部１０が設けられている。凹溝部１０は、下方に略Ｖ字状に凹設されている（図３参照）。
本実施形態では、凹溝部１０は、フロア開口部５の車幅方向で側方に、車体前後に延びる直線部１１と、直線部１１と連続して、フロア開口部５の後側に廻込む曲線部１２とを有している。
このため、図２に示すように、本実施形態の凹溝部１０は、平面視で略逆Ｊ字状となり、フロア開口部５の周縁部５ａを囲んでいる。 Further, the floor panel 2 is provided with a concave groove portion 10. The concave groove portion 10 is recessed downward in a substantially V shape (see FIG. 3).
In the present embodiment, the concave groove portion 10 wraps around the floor opening 5 laterally in the vehicle width direction in succession with the straight portion 11 extending to the front and rear of the vehicle body and the straight portion 11 to the rear side of the floor opening 5. It has a curved portion 12.
Therefore, as shown in FIG. 2, the concave groove portion 10 of the present embodiment has a substantially inverted J shape in a plan view and surrounds the peripheral edge portion 5a of the floor opening 5.

また、凹溝部１０の直線部１１とフロア開口部５との間には、高剛性部１５が形成されている。高剛性部１５は、直線部１１とフロア開口部５との間で、上下方向からフロアパネル２に接合される長尺状のパッチ１６を有している。そして、高剛性部１５は、フロア開口部５の周縁部５ａを車両前後方向に補強している。
本実施形態のパッチ１６は、長尺平板形状の金属製で、長手方向に複数の山部と谷部とを交互に繰り返して形成されている。このうち、谷部には、所定の間隔を置いて下方に凸の複数の接合部１６ａ〜１６ｄが設けられている。 Further, a high rigidity portion 15 is formed between the straight portion 11 of the concave groove portion 10 and the floor opening 5. The high-rigidity portion 15 has a long patch 16 joined to the floor panel 2 from the vertical direction between the straight portion 11 and the floor opening 5. The high-rigidity portion 15 reinforces the peripheral edge portion 5a of the floor opening 5 in the front-rear direction of the vehicle.
The patch 16 of the present embodiment is made of a long flat plate-shaped metal, and is formed by alternately repeating a plurality of peaks and valleys in the longitudinal direction. Of these, a plurality of downwardly convex joints 16a to 16d are provided in the valleys at predetermined intervals.

図３に示すように、フロア開口部５の周縁部５ａの略全周は、フロアパネル２の他の部位よりも一段高く形成されている。また、周縁部５ａのうち、直線部１１とフロア開口部５との間には、他の周縁部５ａの部位よりもさらに一段高く膨出して、平坦な上面を有する接合座面１５ａ〜１５ｃが車両前後方向に所定の間隔を置いて形成されている（図１参照）。
そして、各接合座面１５ａ〜１５ｃには、パッチ１６の接合部１６ａ〜１６ｃがそれぞれ上方から重合されて接合されている。これにより、フロアパネル２とパッチ１６の各山部との間には、所定の大きさの間隙がそれぞれ形成されている。 As shown in FIG. 3, substantially the entire circumference of the peripheral edge portion 5a of the floor opening 5 is formed to be one step higher than the other portions of the floor panel 2. Further, among the peripheral edges 5a, between the straight line portion 11 and the floor opening 5, joint seat surfaces 15a to 15c which bulge one step higher than the other peripheral edges 5a and have a flat upper surface are formed. They are formed at predetermined intervals in the front-rear direction of the vehicle (see FIG. 1).
Then, the joint portions 16a to 16c of the patch 16 are polymerized and joined to each of the joint seat surfaces 15a to 15c from above. As a result, a gap having a predetermined size is formed between the floor panel 2 and each mountain portion of the patch 16.

また、図２に示すように本実施形態のフロア開口部５の前側には、クロスメンバ２０が車幅方向に延設されている。クロスメンバ２０は、車両前後方向の断面形状を略ロ字状として長尺状を呈している。また、クロスメンバ２０は、車幅方向の左，右両端をサイドシル３，３にそれぞれ接合している。そして、クロスメンバ２０は、フロアパネル２の上面から上方に所定の高さで凸設されている（図１参照）。
そして、本実施形態のフロアパネル２は、クロスメンバ２０とフロア開口部５の間に延設された上向きに凸のビード３０をさらに備えている（図５参照）。本実施形態のビード３０は、クロスメンバ２０とフロア開口部５の周縁部５ａとを接続している。 Further, as shown in FIG. 2, a cross member 20 extends in the vehicle width direction on the front side of the floor opening 5 of the present embodiment. The cross member 20 has a long shape with a substantially square cross-sectional shape in the front-rear direction of the vehicle. Further, the cross member 20 has both left and right ends in the vehicle width direction joined to the side sills 3 and 3, respectively. The cross member 20 is projected upward from the upper surface of the floor panel 2 at a predetermined height (see FIG. 1).
The floor panel 2 of the present embodiment further includes an upwardly convex bead 30 extending between the cross member 20 and the floor opening 5 (see FIG. 5). The bead 30 of the present embodiment connects the cross member 20 and the peripheral edge portion 5a of the floor opening 5.

本実施形態のビード３０は、図２に示す上面視で、車両前後方向に沿う直線から中心軸を左側方に約４５度、傾斜させてクロスメンバ２０に近づくほど外側に延設されている。
さらに、本実施形態のビード３０は、クロスメンバ２０およびフロア開口部５の周縁部５ａにそれぞれ連結されている。
このうち、クロスメンバ２０側には、比較的剛性の高い前側座面部３２が上方に膨出するように形成されている。
また、周縁部５ａ側には、比較的高剛性の蓋体座面部３３が上方に膨出するように形成されている。 In the top view shown in FIG. 2, the bead 30 of the present embodiment is inclined outward by about 45 degrees from the straight line along the vehicle front-rear direction by about 45 degrees to the left side and extends outward as it approaches the cross member 20.
Further, the bead 30 of the present embodiment is connected to the cross member 20 and the peripheral edge portion 5a of the floor opening 5, respectively.
Of these, on the cross member 20 side, a front seat surface portion 32 having a relatively high rigidity is formed so as to bulge upward.
Further, on the peripheral edge portion 5a side, a lid seat surface portion 33 having a relatively high rigidity is formed so as to bulge upward.

そして、ビード３０は、さらに延設方向の中間部に下向きに凸となるくぼみ部３１を有している。図６に示すように、くぼみ部３１は、前側座面部３２と蓋体座面部３３との中間部に一体に連設されている。また、くぼみ部３１は、前側座面部３２および蓋体座面部３３の上面よりも低く、下向きに凸となるように形成されている。
さらに、本実施形態のくぼみ部３１は、図２に示すように幅方向寸法が前側座面部３２および蓋体座面部３３よりも小さくなるように形成されている。 The bead 30 further has a recessed portion 31 that is convex downward in the intermediate portion in the extending direction. As shown in FIG. 6, the recessed portion 31 is integrally provided in the intermediate portion between the front seat surface portion 32 and the lid seat surface portion 33. Further, the recessed portion 31 is formed so as to be lower than the upper surface of the front seating surface portion 32 and the lid seating surface portion 33 and to be convex downward.
Further, as shown in FIG. 2, the recessed portion 31 of the present embodiment is formed so that the width direction dimension is smaller than that of the front seat surface portion 32 and the lid seat surface portion 33.

また、本実施形態のフロアパネル２は、補強部材４０をさらに備えている。補強部材４０は、フロア開口部５の後側の形状に適合するように、金属製の平板部材を平面視略凹字状に形成している。また、補強部材４０は、車幅方向寸法Ｗ１を、フロア開口部５の車幅方向寸法Ｗ２より大きく設定している。
そして、補強部材４０は、フロアパネル２の上面部に車両上下方向で重ねて接合される。これにより、補強部材４０は、フロア開口部５の車幅方向全幅で車両前後方向に重複する位置に固定される。 Further, the floor panel 2 of the present embodiment further includes a reinforcing member 40. The reinforcing member 40 is formed by forming a metal flat plate member in a substantially concave shape in a plan view so as to match the shape of the rear side of the floor opening 5. Further, the reinforcing member 40 sets the vehicle width direction dimension W1 to be larger than the vehicle width direction dimension W2 of the floor opening 5.
Then, the reinforcing member 40 is overlapped and joined to the upper surface portion of the floor panel 2 in the vertical direction of the vehicle. As a result, the reinforcing member 40 is fixed at a position where the floor opening 5 overlaps in the vehicle front-rear direction with the entire width in the vehicle width direction.

次に、本実施形態の車両１の下部構造における作用効果について説明する。図１に示すように車両１は、下側に燃料タンク４が配置されたフロアパネル２と、フロアパネル２のうち、ポンプユニット６の上方位置に開口形成されるフロア開口部５と、フロア開口部５の車幅方向で側方に、車体前後に延び下方へ凹設される凹溝部１０と、凹溝部１０とフロア開口部５との間に配置されてフロア開口部５の周縁部５ａを車両前後方向に補強する高剛性部１５とを備える。 Next, the action and effect in the lower structure of the vehicle 1 of the present embodiment will be described. As shown in FIG. 1, the vehicle 1 has a floor panel 2 in which a fuel tank 4 is arranged on the lower side, a floor opening 5 formed in an opening above the pump unit 6 among the floor panels 2, and a floor opening. The concave groove portion 10 extending in the front-rear direction of the vehicle body and recessed downward in the vehicle width direction of the portion 5 and the peripheral edge portion 5a of the floor opening 5 arranged between the concave groove portion 10 and the floor opening 5 are provided. A high-rigidity portion 15 for reinforcing in the front-rear direction of the vehicle is provided.

かかる構成の車両１の下部構造では、フロア開口部５の周縁部５ａの下方への変形を制御してフロア下方に配置された燃料タンク４の主にポンプユニット６への干渉を防止することができる。
すなわち、図４に示すように、車両１の側方から入力した荷重は、サイドシル３からフロアパネル２へほぼ水平に伝達される（矢印ａ）。フロアパネル２のフロア開口部５の手前には、下向きに凹設された凹溝部１０および、高剛性部１５が存在する。このため、凹溝部１０を基点として、荷重は下方に伝達されて、フロアパネル２を沈むように屈曲させる（矢印ｂ）。
この際、形状を維持しようとする高剛性部１５を支点として、フロア開口部５の周縁部５ａは、上方へ向けて持上げられる（矢印ｃ）。
したがって、フロアパネル２の下方に燃料タンク４のポンプユニット６が配置されていても、周縁部５ａがポンプユニット６に干渉しにくい。 In the lower structure of the vehicle 1 having such a configuration, it is possible to control the downward deformation of the peripheral edge portion 5a of the floor opening 5 to prevent the fuel tank 4 arranged below the floor from interfering mainly with the pump unit 6. it can.
That is, as shown in FIG. 4, the load input from the side of the vehicle 1 is transmitted substantially horizontally from the side sill 3 to the floor panel 2 (arrow a). In front of the floor opening 5 of the floor panel 2, there are a recessed groove portion 10 recessed downward and a high-rigidity portion 15. Therefore, the load is transmitted downward from the concave groove portion 10 as a base point, and the floor panel 2 is bent so as to sink (arrow b).
At this time, the peripheral edge portion 5a of the floor opening 5 is lifted upward with the high-rigidity portion 15 for maintaining the shape as a fulcrum (arrow c).
Therefore, even if the pump unit 6 of the fuel tank 4 is arranged below the floor panel 2, the peripheral edge portion 5a is unlikely to interfere with the pump unit 6.

このように、本実施形態の車両１の下部構造では、フロア開口部５の周縁部５ａの変形方向を制御することができる。そして、周縁部５ａの変形を制御して、上方へ向けて持上げるように変形させる。これにより、燃料タンク４の上部に配置されたポンプユニット６へ周縁部５ａが干渉することを防止できる。
このため、車室８内側からメンテナンスを行う際に、フロア開口部５を介して点検者は直接、フロア開口部５の周縁部５ａと車両上下方向でほぼ同じ高さ位置に配置（図３参照）されているポンプユニット６の点検や機器の交換を良好なアクセス性で行える。 As described above, in the lower structure of the vehicle 1 of the present embodiment, the deformation direction of the peripheral edge portion 5a of the floor opening 5 can be controlled. Then, the deformation of the peripheral edge portion 5a is controlled to be deformed so as to be lifted upward. As a result, it is possible to prevent the peripheral edge portion 5a from interfering with the pump unit 6 arranged above the fuel tank 4.
Therefore, when performing maintenance from the inside of the vehicle interior 8, the inspector directly arranges the peripheral portion 5a of the floor opening 5 at a substantially same height position in the vehicle vertical direction through the floor opening 5 (see FIG. 3). ) Can be inspected and the equipment can be replaced with good accessibility.

また、図２に示すように、フロアパネル２に接合された長尺状のパッチ１６によって高剛性部１５が構成されている。このため、パッチ１６の形状や大きさ、または、接合箇所によってより変形の制御を容易に行うことができる。 Further, as shown in FIG. 2, the high-rigidity portion 15 is formed by a long patch 16 joined to the floor panel 2. Therefore, deformation can be more easily controlled depending on the shape and size of the patch 16 or the joint portion.

本実施形態の車両１の下部構造では、パッチ１６が長尺平板形状に形成されている。パッチ１６は、長手方向に複数の山部と谷部とを交互に繰り返して、谷部に設けられた複数の接合部１６ａ〜１６ｄをフロアパネル２からそれぞれ膨出形成された各接合座面１５ａ〜１５ｃに上下方向で接合している。
このため、フロアパネル２の上面とパッチ１６の各山部との間には、所定の大きさの間隙がそれぞれ形成されている。したがって、長尺平板形状のパッチ１６であっても間隙を形成しないフロアパネル２との接合の場合と比較して、良好な部材効率で剛性を向上させることができる。 In the lower structure of the vehicle 1 of the present embodiment, the patch 16 is formed in a long flat plate shape. The patch 16 alternately repeats a plurality of peaks and valleys in the longitudinal direction, and each of the joint seating surfaces 15a formed by bulging the plurality of joints 16a to 16d provided in the valleys from the floor panel 2. It is joined to ~ 15c in the vertical direction.
Therefore, a gap having a predetermined size is formed between the upper surface of the floor panel 2 and each mountain portion of the patch 16. Therefore, even if the patch 16 has a long flat plate shape, the rigidity can be improved with good member efficiency as compared with the case of joining with the floor panel 2 which does not form a gap.

本実施形態の高剛性部１５では、パッチ１６をフロアパネル２の上面に接合することにより、コストの上昇を抑制しつつ、凹溝部１０とフロア開口部５の周縁部５ａとの間の狭い範囲を直線状に補強して剛性を向上させることができる。
このため、さらにフロア開口部５の周縁部５ａの変形方向および変形量を容易に制御することができる。 In the high-rigidity portion 15 of the present embodiment, by joining the patch 16 to the upper surface of the floor panel 2, a narrow range between the concave groove portion 10 and the peripheral edge portion 5a of the floor opening 5 is suppressed while suppressing an increase in cost. Can be reinforced linearly to improve rigidity.
Therefore, the deformation direction and the amount of deformation of the peripheral edge portion 5a of the floor opening 5 can be easily controlled.

さらに、図６に示すように、フロア開口部５の後側に設けられるクロスメンバ２０と、クロスメンバ２０とフロア開口部５の間に延設された、上に凸のビード３０とを備えている。ビード３０は、延設方向の中間部に、下向きに凸となるくぼみ部３１を形成している。本実施形態のフロアパネル２では、ビード３０のクロスメンバ２０およびフロア開口部５の周縁の中間部に下向きに凸となるくぼみ部３１を形成している。
かかる構成の本実施形態の車両１では、図５に示すように車幅方向外側から伝達される荷重によって、起点となるビード３０の中心軸の延設方向を尾根としながら水平方向両側から圧縮されて上方に屈曲変形する。
この際、図６に示すようにクロスメンバ２０から伝達された荷重によってビード３０のくぼみ部３１が折曲がり変形の起点となって、くぼみ部３１を下方に沈ませるように屈曲させる。このため、くぼみ部３１の両側に位置する前側座面部３２と、周縁部５ａ側に設けられた蓋体座面部３３は相対的に上方へ盛上がるように変形する。
このため、蓋体座面部３３に連結されている周縁部５ａは、上方向に変形して所望の制御が可能となる。したがって、周縁部５ａがフロア下方に配置された部品へ干渉することがない。 Further, as shown in FIG. 6, a cross member 20 provided on the rear side of the floor opening 5 and an upwardly convex bead 30 extending between the cross member 20 and the floor opening 5 are provided. There is. The bead 30 forms a recessed portion 31 that is convex downward in the middle portion in the extending direction. In the floor panel 2 of the present embodiment, a recess portion 31 that is convex downward is formed in the middle portion of the cross member 20 of the bead 30 and the peripheral edge of the floor opening 5.
In the vehicle 1 of the present embodiment having such a configuration, as shown in FIG. 5, the load transmitted from the outside in the vehicle width direction is compressed from both sides in the horizontal direction with the extension direction of the central axis of the bead 30 as the starting point as the ridge. It bends and deforms upward.
At this time, as shown in FIG. 6, the recessed portion 31 of the bead 30 becomes the starting point of bending deformation due to the load transmitted from the cross member 20, and the recessed portion 31 is bent so as to sink downward. Therefore, the front seat surface portions 32 located on both sides of the recessed portion 31 and the lid seat surface portion 33 provided on the peripheral edge portion 5a side are deformed so as to be relatively raised upward.
Therefore, the peripheral edge portion 5a connected to the lid seat surface portion 33 is deformed upward to enable desired control. Therefore, the peripheral edge portion 5a does not interfere with the parts arranged below the floor.

そして、図２に示すように、フロア開口部５の後側に補強部材４０が設けられている。
補強部材４０は、車幅方向寸法を、フロア開口部５の車幅方向寸法より大きく設定している。また、補強部材４０は、フロア開口部５の車幅方向全幅で車両前後方向に重複する位置に設けられている。
このように構成された本実施形態の車両１では、フロア開口部５の車幅方向全幅で補強部材４０が周縁部５ａを補強する。したがって、側方から荷重が加わる際、フロア開口部５の変形を抑制することができる。 Then, as shown in FIG. 2, a reinforcing member 40 is provided on the rear side of the floor opening 5.
The reinforcing member 40 has a vehicle width direction dimension larger than the vehicle width direction dimension of the floor opening 5. Further, the reinforcing member 40 is provided at a position where the floor opening 5 overlaps in the vehicle front-rear direction with the entire width in the vehicle width direction.
In the vehicle 1 of the present embodiment configured as described above, the reinforcing member 40 reinforces the peripheral edge portion 5a in the entire width of the floor opening 5 in the vehicle width direction. Therefore, when a load is applied from the side, the deformation of the floor opening 5 can be suppressed.

本実施形態では、フロアパネル２の下側に部品としての燃料タンク４が配置されている。しかしながら、特にこれに限らず、部品としては、蓄電池、蓄電池モジュールや燃料電池、燃料電池スタック等、あるいは電装部品等、どのような部品であってもよく、フロアパネル２の下側に装着されて、上部にフロア開口部５が開口形成されるものであればよい。
また、高剛性部１５は、どのような形状および数量のパッチ１６であってもよく、パッチを有していなくてもよい。すなわち、凹溝部１０とフロア開口部５との間に配置されてフロア開口部５の周縁部５ａを車両前後方向に補強していればよい。
たとえば、フロアパネル２に直接、車幅方向に延びるビード部が形成されているものや、あるいは、数枚の板材を重合させた補強部材等の他の部品によって補強するものであってもよく、パッチ１６の数量、形状および材質が特に限定されるものではない。 In the present embodiment, the fuel tank 4 as a component is arranged under the floor panel 2. However, the component is not particularly limited to this, and the component may be any component such as a storage battery, a storage battery module, a fuel cell, a fuel cell stack, or an electrical component, and is mounted on the lower side of the floor panel 2. Anything may be used as long as the floor opening 5 is formed in the upper part.
Further, the high-rigidity portion 15 may have patches 16 of any shape and quantity, and may not have patches. That is, it may be arranged between the concave groove portion 10 and the floor opening 5 to reinforce the peripheral edge 5a of the floor opening 5 in the front-rear direction of the vehicle.
For example, the floor panel 2 may have a bead portion extending directly in the vehicle width direction, or may be reinforced by other parts such as a reinforcing member obtained by polymerizing several plate materials. The quantity, shape and material of the patch 16 are not particularly limited.

さらに、クロスメンバ２０は、フロア開口部５の前側または後側のうち少なくとも何れか一方に設けられていればよい。
そして、ビード３０の方向は、本実施形態のように車両前後方向に沿う直線から左側方に約斜め４５度に傾いて延設されているものに限らず、どのような方向で、クロスメンバ２０およびフロア開口部５の周縁部５ａ間を接続するものであってもよい。 Further, the cross member 20 may be provided on at least one of the front side and the rear side of the floor opening 5.
The direction of the bead 30 is not limited to the one extending at an angle of about 45 degrees to the left from the straight line along the vehicle front-rear direction as in the present embodiment, and the cross member 20 is extended in any direction. And the peripheral portion 5a of the floor opening 5 may be connected.

また、本実施形態の補強部材４０は、図２に示すように、フロア開口部５の後側に補強部材４０が設けられている。しかしながら、特にこれ限らず、フロア開口部５の前側に補強部材４０が設けられていてもよく、前，後両側に設けられていてもよい。
さらに、補強部材４０は、金属製の平板部材をフロア開口部５の周縁部５ａの形状に適合するように平面視略凹字状としている。しかしながら、特にこれに限らず、たとえば、棒状部材によって、周縁部５ａを補強してもよい。
すなわち、補強部材４０は、フロア開口部５より大きく、かつ、フロア開口部５の車幅方向全幅で車両前後方向に重複する位置に設けられるものであれば、形状、数量および材質が特に本実施形態によって限定されるものではない。 Further, as shown in FIG. 2, the reinforcing member 40 of the present embodiment is provided with the reinforcing member 40 on the rear side of the floor opening 5. However, this is not particularly limited, and the reinforcing member 40 may be provided on the front side of the floor opening 5, or may be provided on both the front and rear sides.
Further, the reinforcing member 40 has a substantially concave shape in a plan view so that the metal flat plate member fits the shape of the peripheral edge portion 5a of the floor opening 5. However, the present invention is not particularly limited to this, and the peripheral edge portion 5a may be reinforced by, for example, a rod-shaped member.
That is, as long as the reinforcing member 40 is larger than the floor opening 5 and is provided at a position where the floor opening 5 overlaps in the vehicle front-rear direction in the entire width direction of the vehicle width, the shape, quantity, and material of the reinforcing member 40 are particularly the same. It is not limited by the form.
