２を確保してエンジンへの燃料供給の欠乏を遅らせる。Further, when the amount of fuel decreases and the fuel tank main body 1 has the inclination illustrated in FIGS. 6 and 7, the fuel liquid level G 1 relatively inclines within the tank main body 1 and the inside of the sub tank main body 2 The fuel liquid level G 2 of the above is relatively inclined at a higher level than the above liquid level G 1 . As shown in FIG. 8, when the fuel level is inclined, the conventional box-shaped sub-tank b shown by the broken line has a fuel level of G 3 , but the sub-tank body 2 of the present invention has a convex shape and a bottom. Since the height of the side portion 12 is low, the liquid volume to be put into q in the figure serves to raise the fuel liquid level in the sub tank main body 2 by ΔG, and the fuel liquid level G 2 is the fuel liquid level of the conventional sub tank b. It is higher than G 3 . In addition, the fuel tank body 1 causes various inclinations, but in any case, the liquid level G
2 to delay the lack of fuel supply to the engine.

ク本体１へ戻ることがない等の効果をもつ。(Effect) In the present invention, the sub-tank body 2 is integrally formed in a convex cross section with a wide area bottom 12 and an upper area 13 having a narrow area above the bottom. A fuel inlet / outlet pipe is formed along a wall surface on one side of the portion, a fuel inlet / outlet opening to the bottom of the fuel tank body is provided on one side of the fuel inlet / outlet pipe, and a communication port opening to the inside is provided on the other side. A fuel tank having the sub-tank main body into which the in-tank pump or the fuel supply pipe is inserted from the upper opening of the upper portion is built in the bottom, and the wide bottom 12 of the sub-tank main body 2 is provided on the bottom of the fuel tank main body 1. By joining and fixing, the attachment to the fuel tank body 1 can be stabilized. Further, the bottom portion 12 can increase the amount of fuel held in the bottom of the sub-tank main body 2, and in the case of the vehicle tilting, it is higher than the liquid level G 1 of the fuel tank main body and higher than the liquid level G 3 of the conventional sub-tank. A high level of the fuel liquid level G 2 can be maintained to prevent engine stalling due to interruption of fuel supply to the engine as much as possible, and the fuel inlet / outlet pipe 8 is provided in the sub tank main body 2
Since it can be provided in a long form in the lower part of the bottom area of the fuel tank, and the inlet / outlet 9 that opens to the fuel tank body 1 can be projected long, the fuel once entering the sub tank body 2 does not return to the fuel tank body 1. And so on.
