Abstract

A fuel filler structure includes a base member, a shutter member, a seal part, and an opening part. The base member includes a fuel filler port and a fuel filler port outer circumferential part which is provided outward further than the fuel filler port. In the shutter member, an opening-closing valve is supported movable to a closed position and an open position. The seal part is arranged between the fuel filler port outer circumferential part and the opening-closing valve when the opening-closing valve is located at the closed position. The opening part connects together an outer surface and an inner surface of the fuel filler port outer circumferential part, and a second opening end of the opening part is arranged at a position that overlaps the opening-closing valve when the opening-closing valve is located at the closed position.

First claim

What is claimed is:

1. A fuel filler structure, comprising:
a base member that is attached to an upper end part of a fuel pipe which supplies fuel to a fuel tank and that includes a fuel filler port in which a fuel filler gun is inserted and a fuel filler port outer circumferential part which is provided radially outward further than the fuel filler port;
a shutter member that is attached to the base member and that is movable to a position at which the fuel filler port is closed and to a position at which the fuel filler port is opened;
a seal part that is arranged between the fuel filler port outer circumferential part and the shutter member when the shutter member is located at the position at which the fuel filler port is closed;
an opening part that is formed on the fuel filler port outer circumferential part and that connects together a first surface of the fuel filler port outer circumferential part positioned on an insertion side of the fuel filler gun and a second surface of the fuel filler port outer circumferential part positioned on a side of the shutter member;
a fuel filler port protrusion part that extends in a circumferential direction along an opening surface of the fuel filler port and that protrudes toward the shutter member from a vicinity of the opening surface when the shutter member is located at the position at which the fuel filler port is closed; and
a shutter member protrusion part that is formed on the shutter member and that extends in a circumferential direction along the fuel filler port protrusion part at a radially outer side than the fuel filler port protrusion part and protrudes toward the fuel filler port outer circumferential part when the shutter member is located at the position at which the fuel filler port is closed,
wherein an opening end that opens to the side of the shutter member of the opening part is arranged at a position that overlaps the shutter member in a view from the insertion side of the fuel filler gun when the shutter member is located at the position at which the fuel filler port is closed, and
the opening part opens radially outward further than the fuel filler port protrusion part.

2. The fuel filler structure according to claim 1 ,
wherein the opening part is provided at one or more positions in a vicinity of a lower end part in a vehicle vertical direction of the fuel filler port and
includes a lower surface that is formed on a lower side in a vehicle vertical direction of the opening part and that is tilted downward relative to a horizon in accordance with a direction from the second surface to the first surface.

3. The fuel filler structure according to claim 1 ,
wherein the fuel filler port has a diameter which is smaller than an inner diameter of the seal part.

4. The fuel filler structure according to claim 1 ,
wherein the shutter member includes a projection part that protrudes toward the insertion side of the fuel filler gun at a radially inner side of the fuel filler port when the shutter member is located at the position at which the fuel filler port is closed.
