Abstract
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.
Claims4
A fuel filler structure for a fuel tank, comprising:
- a fuel fill inlet member that is equipped with a fuel fill inlet into which a fuel nozzle for fueling a fuel tank is inserted;
- an opening and closing valve that can open and close the fuel fill inlet;
- a valve shaft for attaching the opening and closing valve to the fuel fill inlet member in such a way that the opening and closing valve can rotate between a closed position, in which it closes the fuel fill inlet, and an open position, in which it opens the fuel fill inlet as a result of being pushed by the fuel nozzle;
- a valve biasing member that biases the opening and closing valve from the open position to the closed position;
- and
- a damper which, when the opening and closing valve rotates from the open position to the closed position, contacts the opening and closing valve on a near side of the opening and closing valve in a direction in which the fuel nozzle is inserted into the fuel fill inlet member and generates resistance in the rotation of the opening and closing valve.
