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.
