上記トンネル部８とサイドシル９とフロントクロスメン
バ11、リヤクロスメンバ12とで囲まれるフロアパネル本
体１の一般部には開口部13を形成してある。An opening 13 is formed in a general portion of the floor panel body 1 surrounded by the tunnel portion 8, the side sill 9, the front cross member 11 and the rear cross member 12.
上記開口部13には周縁フランジ14を有段形成してあり、
この周縁フランジ14上にパネル部材15を取付けて、上記
開口部13を覆うようにしている。A peripheral flange 14 is formed stepwise in the opening portion 13,
A panel member 15 is attached on the peripheral flange 14 so as to cover the opening 13.
尚、上記トンネル部８の側部にはシートスライドレール
16を固定してあり、フロントクロスメンバ11上面に設け
たシート取付孔17と共に図外のシートにより荷重がフロ
アパネル本体１の一般部に直接作用するのを防止してい
る。A seat slide rail is provided on the side of the tunnel portion 8.
16 is fixed, and a seat (not shown) together with a seat mounting hole 17 provided on the upper surface of the front cross member 11 prevents a load from directly acting on a general portion of the floor panel body 1.
上記パネル部材15は、第２，３図に示すように、剛性を
付与するための金網（多数の孔を穿設した鋼板、所謂
「パンチングメダル」も含む）18を芯材として用いたも
のであつて、金網18の上面にはフロアカーペツト19を敷
設してある。また、上記金網18の下側にはゴム等の弾性
材20を重合して、この弾性材20と上記金網18との間に空
間部21を形成してある。したがつて、この空間部21が空
気層として機能することとなる。As shown in FIGS. 2 and 3, the panel member 15 uses a wire net 18 (including a steel plate with a large number of holes, a so-called “punching medal”) 18 for imparting rigidity as a core material. A floor carpet 19 is laid on the upper surface of the wire net 18. Further, an elastic material 20 such as rubber is superposed on the lower side of the metal net 18 to form a space 21 between the elastic material 20 and the metal net 18. Therefore, the space 21 functions as an air layer.
このように構成されたパネル部材15を前記フロアパネル
本体１の開口部13の周縁フランジ14に固定用リテーナ22
を介して取付ネジ23によつて固定してある。The retainer 22 for fixing the panel member 15 thus configured to the peripheral flange 14 of the opening 13 of the floor panel body 1
It is fixed by a mounting screw 23 through.
尚、上記固定用リテーナ22は金網18の全周に配置してあ
つて取付ネジ23により締付けることで床下からの水等の
浸入を阻止するようになつている。The fixing retainer 22 is arranged around the entire circumference of the wire netting 18 and then tightened with a mounting screw 23 to prevent water or the like from entering under the floor.
上記実施例構造によれば、パネル部材15を部分的に使用
し、金網18を剛性材として使用しているため鋼板を剛性
材として使用した場合に比較して車体を軽量化すること
ができる。According to the structure of the above-described embodiment, since the panel member 15 is partially used and the wire netting 18 is used as a rigid material, the weight of the vehicle body can be reduced as compared with the case where a steel plate is used as the rigid material.
この場合、パネル部材15を取付ける部位は、フロアパネ
ル本体１の一般部であり、トンネル部８、サイドシル
９、フロントクロスメンバ11、リヤクロスメンバ12等の
車体骨格部材の配置に影響を与えないため車体のアンダ
ボデイの強度剛性を低下させるようなことはない。In this case, the part to which the panel member 15 is attached is the general part of the floor panel body 1, and does not affect the arrangement of the vehicle body frame members such as the tunnel part 8, the side sill 9, the front cross member 11, the rear cross member 12 and the like. It does not reduce the strength and rigidity of the underbody of the vehicle body.
また、金網18を用いることによつて共振点が移動するた
め、鋼板材を使用した場合のように制振材が必要なくな
り、その点でも車体軽量化に寄与でき、コストダウンを
も図れる。In addition, since the resonance point is moved by using the wire net 18, a vibration damping material is not required as in the case of using a steel plate material, and in that respect as well, it is possible to contribute to weight reduction of the vehicle body and cost reduction.
そして、弾性材20を下側に配置し、この弾性材20と金網
18との間に空間部21を形成することにより、この空間部
21が防音機能を発揮し、その結果、フエルトを廃止で
き、軽量化とコストダウンに寄与できる。Then, the elastic material 20 is arranged on the lower side, and the elastic material 20 and the wire mesh are
By forming a space 21 between the space 18 and
21 has a soundproof function, and as a result, the felt can be eliminated, contributing to weight reduction and cost reduction.
また、パネル部材15の下面に弾性材20を配置してあるた
め、石はね等により付与される衝撃を十分に吸収するこ
とができるという効果がある。Further, since the elastic material 20 is arranged on the lower surface of the panel member 15, there is an effect that it is possible to sufficiently absorb the impact given by a stone splash or the like.
