目的を達成するものである。This invention forms a tunnel in the longitudinal direction of the vehicle that protrudes directly upward from the floor panel in the center of the width direction of the floor panel, and also has one end attached to the upper end of the lower end and the inner and outer surfaces of the tunnel on one side in the width direction. A plurality of tank bands are arranged in the longitudinal direction of the tunnel, the other end of which is attached to the vicinity of the lower end of the other inner surface of the tunnel, and the tank band is used to carry multiple fuel tanks within the tunnel. A curved portion is formed in the tank band corresponding to a lower corner of the fuel tank near the one inner surface of the tunnel, and the tank band is not supported in the direction of one side and the upper surface. The above object is achieved by providing a binge joint at a position and making the other end swingable.
以下本発明の実施例を図面を参照して説明する。Embodiments of the present invention will be described below with reference to the drawings.

ある。As shown in the figure, in this embodiment, a tunnel 2 in the longitudinal direction of the vehicle that projects upward from the floor panel surface is formed in the widthwise center of a floor panel 10 of an automobile (not shown in its entirety). One inner side in the width direction 2
A tank band 21r has one end attached to the upper part of the person's lower end and the other end attached to the vicinity of the lower end of the other inner surface 2B of the tunnel 2. Inside the tunnel 2, the fuel tank 4 is fastened and supported by the tank band 3 toward one side 2B and the top surface 20 inside the tunnel 2, and the tank band 3 is attached to the one inner side of the tunnel 2. A curved part 3A corresponding to the four people is formed at the lower corner of the fuel tank 4 that is close to the two people, and a binge joint 5 is arranged at a position adjacent to the upper part of the curved part 3A to include the curved part 3A. The other end side is made swingable.

とするようにされている。That is, the horizontal portion 3B connected to the tunnel 2 and the fuel tank 4 bulge presses the bottom right corner 4A and the bottom surface 4B of the fuel tank 4 in the tunnel 2, as shown in FIG. , when the free end 30 is fastened to the inclined part IA of the floor panel 1 by the bolt 6 and nut 7, the fuel tank 4 is attached to the inner surface 2B of the tunnel 2.
and the upper surface 20 via the cushioning material 8. When 〇, the lower corner of the fuel tank 4 is located inside the slope IB opposite to the slope IA leading from the floor panel 1 to the tunnel 2. - The space 10 formed near the four people prevents the three people from interfering with the floor panel 1 at the curved part of the tank band 3, and the fuel tank 40 is sometimes assembled using bolts. 5 is designed to facilitate the work.

ナツト７により、フロアパネル１の傾斜部ＩＡに締付は
固定する。When assembling the fuel tank 4 into the tunnel 2, the tank band 3 is released in advance, and the fuel tank 4 is lifted from below so as to be pressed against the inner surface 2B and upper surface 2C of the tunnel 2 via the cushioning material 8. . After that, the tank band 3 is attached to its curved part 3A and horizontal part 3B.
The free end 30 is tightened and fixed to the inclined part IA of the floor panel 1 with the bolt 6 and nut 7.
したがって、燃料タンク４の組付は作業は、非常に簡単
となる。Therefore, the work of assembling the fuel tank 4 becomes very simple.

な上方への膨出かない場合にも適用されるものである。As shown in FIG. 1, the fuel tank 4 in the tunnel 2 is bulged upward on the side of the passenger seat 12, which increases the capacity of the fuel tank 4 and also increases the capacity of the tunnel 2. The upper surface can be used as an armrest for the occupant, and the present invention is also applicable to cases where the upper surface does not bulge upward.
また前記シフトリ／ケージ１４は、車両後方の変速機に
