The present invention relates to an apparatus for opening and closing a fuel lid of a vehicle, comprising: a housing; a push rod arranged in the housing to reciprocate between an open position and a closed position wherein the fuel lid of the vehicle is open at the open position and is closed at the closed position; and a locking unit configured to lock the push rod such that the push rod does not move from the closed position to the open position. The locking unit includes: a drive motor, held in the housing, configured to rotate in forward and reverse directions to correspond to the open position and the closed position; a pinion gear mounted on a shaft of the drive motor to rotate in forward and reverse directions; a linear moving body having a plurality of gear teeth formed to be engaged with the pinion gear in one direction and a locking protrusion formed to protrude toward the push rod and configured to linearly reciprocate by the forward and reverse rotation of the pinion gear; a locking recess formed on a partial region of the outer circumferential surface of the push rod such that the locking protrusion is locked; and a guide unit guiding linear reciprocating movement of the linear moving body in the direction perpendicular to an axis line of the push rod. The present invention can decrease the number of parts to achieve a reduction in the number of assembly steps and enhance assembly efficiency.

    본 발명은 차량의 연료 뚜껑 개폐장치에 관한 것으로서, 하우징; 상기 하우징에 마련되어, 차량의 연료 뚜껑이 개방되는 개방위치와 폐쇄되는 폐쇄위치 사이를 왕복이동하는 푸시 로드; 및 상기 푸시 로드가 상기 폐쇄위치에서 상기 개방위치로 이동하지 않도록 상기 푸시 로드를 로킹하는 로킹부를 포함하며, 상기 로킹부는, 상기 하우징에 수용되어, 상기 개방위치와 상기 폐쇄위치에 대응하여 정역회전하는 구동 모터; 상기 구동 모터의 축에 장착되어 정역회전하는 피니언 기어; 일방향으로 상기 피니언 기어와 맞물리도록 형성된 복수의 기어 이빨과, 상기 푸시 로드를 향해 돌출 형성된 로킹돌기를 가지며, 상기 피니언 기어의 정역회전에 의해 직선왕복이동하는 리니어 이동체; 상기 푸시 로드의 외주 일 영역에 마련되어, 상기 로킹돌기가 로킹되는 로킹홈; 및 상기 리니어 이동체가 상기 푸시 로드의 축선에 대해 직교하는 방향으로 직선왕복이동하도록 안내하는 가이드부를 포함하는 것을 특징으로 한다.
