おそれがある。 However, in such a conventional fuel tank device for a vehicle, when an impact load F is applied to the vehicle body from one direction of the pin joint of the suspension member 2, an inertial force F' acts on the fuel tank 3, and the suspension member 2 absorbs the fuel. It is pushed in the F' direction by the tank 3 and rotates around the pin joint 1. As a result, fuel tank 3
As shown in Figure 2, there is a risk that the fuel will move significantly in the F' direction, causing fuel leakage in the event of a collision due to interference with surrounding parts.

燃料タンクフランジ部３の折れ曲がりが大きく、
やはり燃料漏れなどを招くおそれがある。 Therefore, it has been proposed that a reinforcing member is interposed between the fuel tank 3 and the vehicle body floor 5 to suppress the movement of the fuel tank 3. However, with such conventional means, the fuel tank The deformation of the fuel tank itself and the bending of the fuel tank flange part 3 are large.
After all, there is a risk of fuel leakage.
本考案は、このような問題点を解決しようとす

を目的とする。 The present invention is an attempt to solve these problems.The impact load applied to the vehicle due to a collision, rear-end collision, etc. causes the fuel tank to move significantly in the direction of load input, causing deformation due to interference with surrounding components. In order to prevent damage, the suspension member that restrains the fuel tank so that it can move relative to the vehicle body is prevented from moving along the longitudinal direction of the vehicle body using a reinforcing member, which acts on the vehicle due to a collision, rear-end collision, etc. Even if the fuel tank moves due to an impact load and collides with the intermediate part of the suspension member, the suspension member is prevented from deforming or moving, and at the same time, the movement of the fuel tank is suppressed, and the fuel tank is An object of the present invention is to provide a holding structure for a fuel tank for a vehicle, which can prevent deformation and damage to the fuel tank and the occurrence of fuel leakage caused by the deformation and damage.
このため、本考案の車両用燃料タンクの保持構

とを特徴としている。 Therefore, in the vehicle fuel tank holding structure of the present invention, a band-shaped suspension member is arranged along the longitudinal direction of the vehicle body, and both ends of the suspension member are fixed to the vehicle body via fixing means. In the holding structure for a vehicle fuel tank, which restrains a fuel tank between the vehicle body and the suspension member so as to be movable relative to the vehicle body, the suspension member is secured between an intermediate portion of the suspension member and the vehicle body. The present invention is characterized in that a reinforcing member is installed to restrict movement of the vehicle body in the longitudinal direction.
以下、図面により本考案の一実施例としての車
両用燃料タンクの保持構造について説明すると、
第３図はその配設状態を一部断面で示す側面図、
第４図はその作用を第３図に対応させて示す側面
図であつて、第３，４図中、第１，２図と同じ符
号はほぼ同様の部分を示す。 Hereinafter, a holding structure for a vehicle fuel tank as an embodiment of the present invention will be explained with reference to the drawings.
Figure 3 is a side view showing the arrangement state with a partial cross section;
FIG. 4 is a side view showing the operation corresponding to FIG. 3, and in FIGS. 3 and 4, the same reference numerals as in FIGS. 1 and 2 indicate almost the same parts.
第３図に示すごとく、燃料タンク３は自動車に
おける車体フロア５の段上がり部下側において懸
架部材２を介し拘束されるようにして取付けられ
ている。すなわち懸架部材２は、帯状に形成され
て、その一端が車体フロア５の下側付きのブラケ
ツト５ａにピンジヨイント１を介して枢着され、
その中間部が燃料タンク３の外側部に装着され、
その他端がボルト６とナツト７とで上記一端部よ

されることによつて、燃料タンク３を車体フロア
５に拘束している。 As shown in FIG. 3, the fuel tank 3 is attached to the lower side of the stepped rise of the vehicle body floor 5 of an automobile so as to be restrained via a suspension member 2. As shown in FIG. That is, the suspension member 2 is formed into a band shape, and one end thereof is pivotally connected to a bracket 5a attached to the lower side of the vehicle body floor 5 via a pin joint 1.
The middle part is attached to the outer part of the fuel tank 3,
The fuel tank 3 is restrained to the vehicle body floor 5 by fixing the other end to the lower side of the vehicle body floor 5 at the rear of the vehicle body relative to the one end with a bolt 6 and a nut 7.
なお、懸架部材２は、車幅方向に間隔をあけて
ほぼ平行に複数個配設されている。 Note that a plurality of suspension members 2 are arranged substantially parallel to each other at intervals in the vehicle width direction.
また、車体フロア５の段下がり部下側には、補
強部材４の一端がボルト８によつて固定されてお
り、この補強部材４は車体後方へ向けて突設され
て、その他端が、懸架部材２の外側に取付けられ
たブラケツト２ａにボルト８を介し固定されてい
る。 Further, one end of a reinforcing member 4 is fixed to the lower side of the step down of the vehicle body floor 5 with a bolt 8, and this reinforcing member 4 is provided to protrude toward the rear of the vehicle body, and the other end is connected to a suspension member. It is fixed via bolts 8 to a bracket 2a attached to the outside of 2.
なお、補強部材４は上記のようにして各懸架部
材２にそれぞれ取付けられている。 Note that the reinforcing member 4 is attached to each suspension member 2 as described above.
これにより、例えば懸架部材２のピンジヨイン
ト１方向から車体に衝撃荷重Ｆが加わつて、燃料
タンク３に衝撃的な慣性力F′が作用することによ

しようとしても、この回転は補強部材４によつて
阻止される。このとき慣性力F′は懸架部材２を介
して補強部材４で受けられる。 As a result, for example, an impact load F is applied to the vehicle body from the direction of the pin joint 1 of the suspension member 2, and an impactful inertia force F' acts on the fuel tank 3, causing the suspension member 2 to try to rotate around the pin joint 1. However, this rotation is prevented by the reinforcing member 4. At this time, the inertial force F' is received by the reinforcing member 4 via the suspension member 2.
したがつて、燃料タンク３に上記のような慣性
力F′が作用しても、燃料タンク３は、第４図に示
すごとく、そのフランジ部３ａが懸架部材２に当
つて止まる。 Therefore, even if the above-mentioned inertial force F' acts on the fuel tank 3, the flange portion 3a of the fuel tank 3 hits the suspension member 2 and stops, as shown in FIG.
このように、衝突時等に、車体に衝撃荷重Ｆが
作用した場合でも、燃料タンク３を拘束する懸架
部材２の移動が補強部材４で規制されているた
め、燃料タンク３が移動して懸架部材２に衝突し
ても、懸架部材２が変形移動することがなく、ま
た燃料タンク３の移動も抑制されるので、燃料タ
ンク３が周辺部材と干渉して変形破損するおそれ
もない。 In this way, even if an impact load F is applied to the vehicle body in the event of a collision, etc., the movement of the suspension member 2 that restrains the fuel tank 3 is restricted by the reinforcing member 4, so the fuel tank 3 moves and the suspension is suspended. Even if the suspension member 2 collides with the member 2, the suspension member 2 does not deform and move, and the movement of the fuel tank 3 is also suppressed, so there is no risk that the fuel tank 3 will interfere with surrounding members and be deformed or damaged.
さらに、燃料タンク３は、車体に対して移動可
能に拘束されているため、追突や衝突等で車体が
変形しても、燃料タンク３が車体の変形の影響を
受けにくく、したがつて燃料タンク３自身が変形
破損することがなく、これにより車両衝突時の安
全性が大幅に向上する。 Furthermore, since the fuel tank 3 is movably restrained relative to the vehicle body, even if the vehicle body is deformed due to a rear-end collision or collision, the fuel tank 3 is not easily affected by the deformation of the vehicle body. 3 itself will not be deformed or damaged, thereby greatly improving safety in the event of a vehicle collision.
なお、補強部材４を、第３，４図に示すように
車体フロア５と懸架部材２の前端部側との間に介
装する代わりに、車体フロア５と懸架部材２の後
端部側との間に介装してもよい。 Note that instead of interposing the reinforcing member 4 between the vehicle body floor 5 and the front end side of the suspension member 2 as shown in FIGS. 3 and 4, the reinforcement member 4 is interposed between the vehicle body floor 5 and the rear end side of the suspension member 2. It may be interposed between.
以上詳述したように、本考案の車両用燃料タン
クの保持構造によれば、衝突時等に、車体に衝撃
荷重が作用した場合でも、燃料タンクを拘束する
懸架部材の移動が補強部材により規制されるた
め、燃料タンクが移動して懸架部材に衝突して
も、懸架部材が変形移動することがない。また燃
料タンクの移動も抑制されるので、燃料タンクが
周辺部材と干渉して変形破損することもない。 As detailed above, according to the vehicle fuel tank holding structure of the present invention, even when an impact load is applied to the vehicle body during a collision, the movement of the suspension member that restrains the fuel tank is restricted by the reinforcing member. Therefore, even if the fuel tank moves and collides with the suspension member, the suspension member will not be deformed or moved. Furthermore, since the movement of the fuel tank is suppressed, the fuel tank does not interfere with surrounding members and become deformed or damaged.
さらに、燃料タンクは、車体に対して移動可能
に拘束されているため、追突や衝突等で車体が変
形しても、燃料タンクが車体の変形の影響を受け
にくく、したがつて燃料タンク自身が変形破損す
ることがなく、これにより車両衝突時の安全性が
大幅に向上する利点がある。 Furthermore, since the fuel tank is movably restrained relative to the vehicle body, even if the vehicle body deforms due to a rear-end collision or collision, the fuel tank is less affected by the deformation of the vehicle body, and therefore the fuel tank itself is There is no deformation or damage, which has the advantage of greatly improving safety in the event of a vehicle collision.
