Fuel tank apparatus
View Patent ↗A fuel tank apparatus is disposed above an engine. The fuel tank apparatus includes a fuel tank in which fuel is stored and a fuel pump coupled to the bottom of the fuel tank. A heat-shield cover that covers a portion of the fuel pump, which portion is exposed from the fuel tank, to shield the portion from heat of the engine is mounted on a coupling portion between the fuel pump and the fuel tank.
1. A fuel tank apparatus, which is disposed above an engine comprising:
a fuel tank;
a fuel pump coupled to a bottom of the fuel tank; and
a heat-shield cover mounted at a coupling portion between the fuel pump and the fuel tank, the heat-shield cover covering a portion of the fuel pump, the portion of the fuel pump being exposed from the fuel tank, to shield the portion of the fuel pump from heat of the engine, wherein
the fuel pump includes: a pump main body; and a pump flange that is provided on a lower portion of the pump main body and coupled to the bottom of the fuel tank,
the coupling portion surrounds the pump flange,
the heat-shield cover covers at least a lower surface of the pump flange,
the heat-shield cover is formed by bending a sheet-like member and includes:
a cover portion that covers the lower surface of the pump flange; and
a mounting portion that is bent to continue from the cover portion so as to be mounted on the pump flange.
2. The fuel tank apparatus as claimed in claim 1 , wherein
the cover portion has therein a through-hole through which a fuel supply pipe extending from the pump main body penetrates, and
a wire for the fuel pump is led from a gap between the cover portion and the mounting portion.
3. The fuel tank apparatus as claimed in claim 1 , wherein
an engagement groove is formed at an end portion of the mounting portion that is on an opposite side of the sheet-like member from the cover portion, and
an engagement piece that is engaged with the engagement groove is formed at an end portion of the cover portion that is on an opposite side of the sheet-like member from the mounting portion.
4. The fuel tank apparatus as claimed in claim 3 , wherein
the engagement piece includes:
an engagement piece main body having a shape of a strip extending in an engagement direction; and
a retaining portion projecting from the engagement piece main body in a widthwise direction of the strip, and
the engagement groove includes:
a short groove through which the engagement piece main body passes along the engagement direction; and
a long groove with which the retaining portion is engaged.
5. The fuel tank apparatus as claimed in claim 1 , wherein
the fuel tank apparatus is disposed between a head pipe and a rider seat of a motorcycle, and
a bending portion of the heat-shield cover that is between the cover portion and the mounting portion is positioned at a front end of the heat-shield cover.
