The present invention relates to a structure of a fuel door. According to an embodiment of the present invention, the structure of a fuel door comprises: a gear (100) formed in the shape of a fan sharing a hinge and a rotating shaft of the fuel door (2); a first spring (200) whose one end is affixed to a housing (1), whose the other end is connected to the gear (100), and which applies elastic force to rotate the gear (100) in a direction to open the fuel door (2); a latch (300) whose one end is combined with the housing (1) with a hinge with a hinge unit (310) as the medium to be parallel to the rotating shaft of the gear (100) and whose one side surface comes in contact with the outer circumferential surface of the gear to prevent the gear from rotating; and a second spring (400) whose one end is affixed to the housing (1), whose the other end comes in contact with the other side surface of the latch (300), and which pushes the latch (300) toward the gear (100). According to the present invention, an opener is removed from the conventional fuel door to reduce costs and weight, to simplify the structure, and to improve opening and closing. |
