Abstract:
A fueling device for fueling a fuel tank through a fuel passage of a fuel filler pipe communicating with the fuel tank, said fueling device comprising:a casing main body disposed in the fuel passage of the fuel filler pipe, said casing main body having an inlet opening for introducing fuel therethrough; a cap main body having a handle, said cap main body being movable by operation of said handle between an open position in which said cap main body is disengagable from said casing main body to permit introduction of fuel through said inlet opening and a closed position in which said cap main body engages said casing main body to obstruct fuel from being introduced through said inlet opening; a shutter coupled to said casing main body and arranged to be disposed in the fuel filler pipe, said shutter being operable to open and close the fuel passage; and a connector that operatively couples said cap main body to said shutter in such a manner that movement of said cap main body to the closed position applies a closing force to said shutter to close said shutter; wherein said casing main body is detachable from the fuel filler pipe and comprises a seal component operable to press against the inner wall of the fuel filler pipe to effect air-tight sealing between said casing main body and the fuel filler pipe, said cap main body is rotatable into the closed position by application of a rotational force to said handle, and said connector comprises a cam unit for converting the rotational force applied by said handle into the closing force, said cam unit comprising: an engagement projection connected to said handle; an insertion hole formed in said shutter, into which said engagement projection is insertable; and a cam surface formed on a surface of said shutter facing away from said handle and operatively associated with said engagement projection when said engagement projection is inserted into said insertion hole to apply the closing force to said shutter in response to the application of the rotational force by said handle.
