摘要:
To obtain a fuel filler structure for a fuel tank wherein when causing an opening and closing valve to close, it can be ensured that the opening and closing valve does not rapidly rotate to a closed position in which it closes a fuel fill inlet, and when causing the opening and closing valve to open, the opening and closing valve can be opened with a small force. A fuel filler structure is equipped with a damper on the near side of a flapper valve in the insertion direction of a fuel nozzle. When the flapper valve rotates to an open position, the damper does not act on the flapper valve, and when the flapper valve rotates to a closed position, the damper acts on the flapper valve.
