漏れ出さないようにしたものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a sub-tank composed of two members, and a sub-tank constructed by joining two members of an upper structure and a lower structure to each other. By forming each structure of the constituent members in a special shape, even if the fuel in the fuel tank is reduced, the fuel does not leak from the joint portion of the two members into the fuel tank.
(従来の技術) 上部構成体と下部構成体の二部材により構成される本考

の補給が不能になる不都合があった。However, when the vehicle runs on a sloping ground or stops on a sloping ground, the fuel tank tilts and the fuel deviates, and it is impossible to send the fuel to the engine by the in-tank pump or the like.
There is a model in which the sub tank S is provided close to the bottom of the fuel tank. This type of sub-tank S is designed to ensure a sufficient amount of fuel to be sent from the sub-tank to the engine even when the vehicle leans and the fuel G moves in the tilting direction as shown in FIG. When the remaining amount of G is small, there is a disadvantage that the fuel cannot be supplied to the engine by the in-tank pump or the fuel supply tube only with the fuel in the sub-tank S.

Since it is necessary to secure a height high enough to be sucked into the sub-tank and increase the fuel holding amount in the sub-tank, its shape is made special by joining two members of the upper structure and the lower structure, Provided is a two-member subtank in which fuel inside does not come into contact with the joint of the two members even if the subtank is tilted so that fuel does not leak even if the joint is not particularly sealed. That is the purpose.

る。The sub tank 11 is an outer wall 12a of the sub tank body 12,
The upper lid portion 13b of the fuel sub-chamber 13 is configured in the upper structural body 15, and the outer wall 13a of the fuel sub-chamber 13 and the bottom wall 11a of the sub tank 11 are configured in the lower structural body 16, which is formed in the upper structural body 15. The upper lid portion 13b that does not have a flat surface as a whole comprises a wall portion 17 that rises from the middle of the upper lid 13b -1 , and a remaining upper lid 13b -2 connected to the upper edge of the wall portion 17 to form a lower structure. The outer wall 13a provided on the upper part 16 has a height that contacts the lower surface of the remaining upper lid 13b -2 ,
Joints 15a and 16a for joining the lower structures 15 and 16 are formed.

る。In the above-described structure, one side of the fuel sub-chamber is used as the fuel passage 18 through which the fuel in the bottom portion of the fuel tank 1 flows in and out.
A passage wall 18a is opened in the outer wall 13a on one side of 18, and a partition wall 19 that is in contact with the outside of the wall portion 17 of the portion and is cut away at a portion opposite to the passage opening 18 is provided at the bottom of the lower structural body 16. It is provided on the wall 11a.

ことができる。As illustrated in FIG. 6, even if the fuel tank 1 and the sub-tank 11 tilt together with the vehicle, the amount of fuel a that can be continuously pumped from the intake port of the in-tank pump to the engine when the vehicle is horizontal. The amount is shown in FIG. If the amount of the fuel a is lower than the height when the sub tank 11 moves due to the inclination of the sub tank 11, the fuel a may leak to the fuel tank 1 side. However, since the present invention makes the joints 15a and 16a have a height that does not cause the above-mentioned leakage, it is not necessary to provide a leak-proof seal. Therefore, the joint portions 15a, 16a
Can also be joined by fitting or the like having no sealing function.

The two members of the structural body 16 are joined, and the upper and lower structural bodies 15, 16 are joined at a position higher than the height at which the required amount of fuel a can be secured in the sub tank 11 even when the sub tank 11 is tilted. Since it has a special configuration that allows the fuel a in the sub-tank 11 to leak to the fuel tank 1 side, there is no need to provide a leak-proof seal. Further, the fuel sub-chamber can increase the amount of bottom fuel possessed, and even when the vehicle is tilted, the fuel level is maintained at a higher level than before and engine stall due to interruption of fuel supply to the engine is possible. It has various effects that can be prevented.
