Abstract
An embodiment fuel cap system includes a filler neck connected to a fuel pipe, a fuel cap having a cylindrical shape and able to be coupled to the filler neck by rotation, a sliding rod extending from an upper surface of the fuel cap in a shaft direction at an inside of the fuel cap and rotatable together with the fuel cap, a plunger including an upper end slidably coupled to the sliding rod in the shaft direction and a lower end including a coupling rod, and an inner ring on the filler neck and including a catching groove having an interior circumference on which the coupling rod is selectively engaged, wherein a rotation of the fuel cap is prevented when the coupling rod is engaged on the catching groove and the rotation of the fuel cap is possible when the coupling rod is disengaged from the catching groove.
