As shown in Figure 8 A, when fuel tank 50 is not tilted relative to horizontal ground level HGL and stored fuel F very little
When, fuel storage is in the region (front area 74a) and the second bottom wall part 76 of the front of the first bottom wall part 74.In this way, when combustion
Doses hour can keep stored fuel to surround the entering part 64 of petrolift 60.
Therefore, because central depression 70 upwardly extend along the longitudinal direction of fuel tank 50 at the middle part of bottom wall 66 (see
Fig. 4), the storage space for being used for fuel F is formed on bottom wall 66, to deposit compared with bottom wall 66 is flat or horizontal situation
The volume of the fuel F of storage sufficiently keeps the operation for petrolift 60.In this way, even if fuel F volume is low, it is stored on bottom wall 66
Fuel F be also capable of supply that entering part 64.
As shown in Figure 8 B, in fuel tank 50 relative to horizontal ground level HGL to the right to tilting and the combustion that is stored
Expect in the lesser situation of F, since central depression 70 is used as the wall of interim storage box, fuel F can be stored in the first bottom wall part
In the region (front area 74a) of 74 front.In this way, stored fuel F can be kept to surround fuel when fuel quantity is small
The entering part 64 of pump 60.
As shown in Figure 8 C, in fuel tank 50 relative under horizontal ground level the HGL to left down inclined situation in direction, because of institute
The fuel F of storage tends to be moved to the first bottom wall part 74 (front area 74a) from the second bottom wall part 76, and fuel F can be stored
In the region (front area 74a) of the front of the first bottom wall part 74.In this way, can be kept stored when fuel quantity is small
Fuel F surrounds the entering part 64 of petrolift 60.
Particularly, it is lower than the rear portion of the first bottom wall part 74 with the front area 74a of the first bottom wall part 74 due to fuel tank 50
The mode of region 74b is formed, and therefore, along hillside or is inclined when fuel tank 50 is when front upper place tilts upwards, such as in motorcycle 10
During the big clinoplain of rake angle travels upwards, the above-mentioned movement about storage fuel F is significant.That is, even if fuel quantity F
Small and fuel tank 50 front upper place to and/or left right tilt upwards, fuel tank 50 also keeps stored fuel F to surround
Fuel inlet portion 64, so that petrolift 60 smoothly operates.
