Abstract

The known fuel tank for straddled type vehicles that is formed to have an inverse U-shaped transverse cross-section with its lower section bifurcated into left and right branch portions so as to straddle a main pipe of the straddled type vehicle from the above, is improved in that at least one of the rear bottom surface and the front bottom surface of either one of the lower bifurcated branch portions of the fuel tank is formed in a slant surface inclined upwards toward the corresponding end of the fuel tank.

Claims

1. A fuel tank for straddle type vehicles which is formed to have an inverse U-shaped transverse cross-section with downwardly extending legs of said U-shaped section bifurcated into left and right branch portions and straddling a main pipe of said straddle type vehicle, said tank having a top surface and front, rear and bottom surfaces;

at least a portion of the bottom surface at one end portion of the surface of one of said downwardly extending legs of said fuel tank slants upwardly forming a slanted fuel guide surface toward a corresponding top surface of said fuel tank and rear and front portions of the bottom surface of the other of said downwardly extending legs is substantially flat.

2. A fuel tank for straddle type vehicles as claimed in claim 1, characterized in that a fuel cock is connected to said other of said downwardly extending legs of said fuel tank.

3. A fuel tank fior straddled type vehicles as claimed in claim 1, characterized in that said fuel guide surface consists of a single smoothly curved surface.

4. A fuel tank for straddle type vehicles as claimed in claim 1, characterized in that said slant surface consists of a lower fuel guide surface portion, an upper slant surface portion and a flat surface portion therebetween which is substantially parallel to the bottom surface of said other of said downwardly extending legs.

5. A fuel tank for straddle type vehicles as claimed in claim 1, wherein said fuel guide surface is twisted as it extends toward the top of said fuel tank in such a manner that one edge of said fuel guide surface may be raised relative to another edge thereof.
