In conventional motorcycles, tricycles, etc., the fuel tank installed between the front fork and the seat has a stay at the front and rear, and an insertion hole with approximately the same diameter as the mounting bolt in the front stay. Elongated insertion holes are formed in each stay. Therefore,
If the dimensions change due to product errors or swelling of the tank due to fuel, the installation condition will be adjusted using the insertion hole in the rear stay, which will create a gap between the seat and the fuel tank, which may be unfavorable in terms of appearance. It is desirable to avoid creating gaps between the seat and the fuel tank, since the driver often sits in front of the seat in vehicles that travel off-road. .

As mentioned above, when the fuel tank of a motorcycle, three-wheeled vehicle, etc. is disposed between the front fork and the seat, this invention forms a long hole in the front and rear direction of the tank in the stay at the front of the fuel tank. Since the elongated hole absorbs dimensional changes in the fuel tank caused by such factors, there is no gap between the fuel tank and the seat, which alleviates the stress acting on each stay and improves the seating comfort of the seat. and improves appearance. In addition, since the mounting portions of the front stay and the rear stay of the fuel tank are formed so as to intersect with the longitudinal direction of the elongated hole and are inclined toward the rear of the vehicle body so as to be approximately parallel to each other, it is possible to When the rider stands or sits in front of the seat while riding, even if the fuel tank is pushed forward by the impact, the slope of the mounting parts of the front stay and rear stay of the fuel tank will not change. Therefore, the pressing force does not directly hit the bolts that fasten the fuel tank, and shearing force does not act directly, resulting in a structure that has excellent durability and impact resistance for the bolts, stays, etc.
Moreover, even if the mounting bolts of the front stay become a little loose and the stay wobbles, the pushing force of the fuel tank toward the front of the vehicle will not directly hit the bolt part as described above, so the pushing force will be that much lower, and the elongated hole in the front stay will can be fully absorbed.
