なる問題もある。 Conventionally, fuel tanks for vehicles have been designed to suppress the shaking of the fuel injected into the fuel tank when the vehicle is running, thereby suppressing shaking noise. As is known, this type of fuel tank is constructed by having a plurality of partition plates installed vertically inside the tank and fixed to the inner wall of the tank body at the peripheral edges other than the bottom surface of the partition plates. That is, since the bottom surface of the fuel tank is not fixed to the lower surface of the partition plate, when a large amount of fuel is injected, the bottom surface bends downward and bulges due to the weight of the fuel. For this reason, in the case of vehicles with low fuel tank ground clearance, the bottom of the fuel tank bulges downward, further lowering the ground clearance and causing the bottom of the fuel tank to interfere with the road surface when driving on rough roads. There are some problems that make it easier. Another problem is that the bottom surface of the fuel tank vibrates up and down, making it easy to hear the sound of the fuel shaking.

孔６，７が同心状に上下に連通する。 In Fig. 2, 4 is a first buttfull on the top side, and 5 is a second buttfull on the lower side.Both buttfulls 4 and 5 are formed by pressing a steel plate into a channel shape in cross section. It consists of side wall parts 4a and 4b and 5a and 5b that face each other, and horizontal parts 4c and 5c that connect these side wall parts 4a and 4b and 5a and 5b. Flange portions 4d 1 , 4d 2 bent outward at one end,
5d 1 and 5d 2 are formed, respectively. Then, connect the flange parts 4d 1 and 4d 2 to the upper surface 1a 1 of the Atsupapan 1A.
By welding to the back side of the upper side, the buttful 4 on the top side extends and is fixed to the lower pan 1B side, and by welding the flange portions 5d 1 and 5d 2 onto the bottom surface 1b 1 of the lower pan 1B, the buttful 5 on the lower side is extended and fixed toward the Atsupapan 1A side. Also,
Atsupapan 1A and lower pan 1B are flange part 1
When a and 1b are joined together by welding, the horizontal parts 4c and 5c of both buttfuls 4 and 5 abut each other, and the through holes 6 and 7 formed in the horizontal parts 4c and 5c are concentric. The top and bottom communicate with each other.

れている。 Reference numeral 8 denotes a connecting member, and the connecting member 8 includes, for example, a nut 8a fixed in advance to the back surface of the horizontal portion 5c of the lower buffle 5 so as to be concentric with the through hole 7.
and a bolt 8b screwed into this nut 8a, and the bolt 8b
It is screwed into the nut 8 through the unit insertion hole 9 formed in a1 . Further, a blind plate 10 is normally attached to the unit insertion hole 9 in a detachable manner.
When the fuel tank 1 is attached to the vehicle body, the blind plate 10 is removed and a fuel gauge unit (not shown) is attached to the unit insertion hole 9.
In the figure, reference numeral 11 indicates a communicating hole, which is appropriately formed in the side wall portions 4a, 4b, and 5a, 5b of both buffles 4,5.

に振動しなくなるので、燃料の揺動音が響かなく
なり、揺動音が抑制される。 In the above configuration, the inside of the fuel tank 1 is partitioned by the upper side bumper 4 and the lower side bumper 5, thereby suppressing the fluctuation of the fuel when the vehicle is running. Also, the top surface 1a 1 of Atsupapan 1A
Since the lower side buttful 5 fixed on the bottom surface 1b1 of the lower pan 1B is connected to the upper side buttful 4 fixed to the back side of the fuel tank 1 by the connecting member 8, Even if a large amount of fuel is injected into the lower pan 1B, the bottom surface 1b1 does not bend downward. Furthermore, the spare tire is attached to the lower surface of the fuel tank 1 like in a van type car, and the tightening force of the spare tire is applied to the lower pan 1.
Even if an upward pushing force acts on the bottom surface 1b 1 of the lower pan 1B, the bottom surface 1b 1 of the lower pan 1B does not bend upward. Furthermore, since the bottom surface 1b1 of the lower pan 1B no longer vibrates up and down, the sound of the fuel swinging no longer resonates, and the swinging noise is suppressed.

ることはない。 Moreover, in this case, the buttfuls 4 and 5 are disposed within the fuel tank 1, and both the buttfuls 4 and 5 have an internal space, and the internal space and the outside of the internal space (inside the fuel tank) are connected to the communication hole 11. Because of the communication via the baffles 4 and 5, fuel can enter each buffle 4 and 5 without any problem, and the capacity of the fuel tank is hardly reduced by the presence of the buffles 4 and 5.

記実施例と同様の効果を奏する。 FIG. 3 shows another embodiment of the coupling member 8, in which a cylindrical portion 11 extending downward is formed in the center of the horizontal portion 4c of the buttful 4 on the top side. A tapered surface 11a that widens upward is formed on the outer periphery of the lower end, and a plurality of vertical slits 11b are formed in the cylindrical portion 11, so that the cylindrical portion 11 can be elastically contracted in the radial direction. . And the horizontal part 5c of the lower side Batsuful 5
A locking hole 12 is formed in the center of the holder. Therefore, by overlapping the thick bread 1A vertically with respect to the lower bread 1B, the tapered surface 11 of the cylindrical portion 11
a is pushed into the locking hole 12, and as a result, the cylindrical portion 11 once contracts in the radial direction, and then elastically returns to fit into the locking hole 12, and the locking portion adjacent to the upper side of the tapered surface 11a The locking step portion 11c is configured to engage with the peripheral edge of the locking hole 12 to connect the buffles 4 and 5, and even with this configuration, the same effects as in the above embodiment can be achieved.

制される利点がある。 As explained above, according to this invention, even if the fuel tank is flat, the buttful on the top side extending toward the lower pan side is fixed to the bottom pan, and the lower pan is fixed to the buttfull on the bottom side. Since the lower buttresses fixed to the bottom are connected by a connecting member, the bottom of the lower pan does not bend downward due to the weight of the fuel, preventing interference with the road surface, and preventing the fuel from flowing. This has the advantage of suppressing rocking noise.

The first and second buttfuls are provided with a buttful, each of which has an inner space, and the inner space and the outside of the inner space (inside the fuel tank) are communicated through a communication hole. Fuel can enter the tank without any problem, and the presence of the first and second buffers can prevent the capacity of the fuel tank from decreasing.
