The present invention relates to an apparatus for preventing the fuel of a vehicle fuel tank from overflowing. The apparatus comprises: a valve unit including a valve body, a housing covering a lower part of the valve body, a float mounted on the valve body to slide up and down, and a vapor line formed on an upper part of the valve body to be opened and closed according to the movement of the float to be selectively connected to a canister, and having a fuel inflow hole provided in a side of the housing; a cover unit coupled to the housing to surround the housing, and having a plurality of windows provided along the outer circumferential surface thereof at a height corresponding to the fuel inflow hole so that fuel flows into the valve unit; and a shielding unit mounted on the outer peripheral surface of the cover unit to shield the opened window, and rotating in the turning direction of a vehicle while being mounted on the cover unit, to form the inflow path of the fuel flowing into the fuel inflow hole. Therefore, the apparatus can prevent the fuel from flowing into the inside of the valve unit and the canister through the fuel inflow hole when the oil level of the fuel tank rises in the turning direction.

    본 발명은 밸브바디, 상기 밸브바디의 하부를 덮는 하우징, 상기 밸브바디에 장착되어 상하로 슬라이딩되는 플로트 및 상기 밸브바디의 상부에 형성되어 상기 플로트의 움직임에 따라 개폐되어 선택적으로 캐니스터 측으로 연결되는 베이퍼 라인으로 구성되며, 상기 하우징의 측면에 마련된 연료 유입 홀을 구비하는 밸브 유닛, 상기 하우징을 감싸도록 결합되고, 상기 연료 유입 홀과 대응되는 높이에서 외주면을 따라 복수개의 윈도우가 구비되어 연료가 상기 밸브 유닛으로 유입되도록 형성되는 커버 유닛 및 상기 커버 유닛의 외주면에 장착되어 개방된 상기 윈도우를 차폐하고, 상기 커버 유닛에 장착된 상태에서, 차량의 선회 방향을 따라 회전하여 상기 연료 유입 홀로 유입되는 연료의 유입 경로를 형성하는 차폐 유닛을 포함한다.
