a fixed ring concentrically formed with the fuel hole and fixed to the door frame; moving panels rotatably fixed to the fixed ring to adjust an opened degree of the fuel hole; a rotator ring concentrically formed with the fixed ring and provided in the door frame so as to rotate based on a center of the fuel hole; and a plurality of links each having a first end hinge-connected to the rotator ring and a second end hinge-connected to a corresponding moving panel, wherein the first end and the second are spaced each other. ### Claim 2 (depends on 1) The fuel cap integrated aperture type fuel door structure according to claim 1, wherein end portions of a plurality of the moving panels pass through a center of the fixed ring. ### Claim 3 (depends on 2) The fuel cap integrated aperture type fuel door structure according to claim 2, wherein the plurality of the moving panels meet each other at the center of the fixed ring to close the fuel hole. ### Claim 4 (depends on 1) The fuel cap integrated aperture type fuel door structure according to claim 1, wherein the fuel hole is connected to a connection pipe part receiving the fuel from an outside to a fuel tank provided in a vehicle. ### Claim 5 (depends on 1) The fuel cap integrated aperture type fuel door structure according to claim 1, wherein the fixed ring is fixed to the door frame so as to be concentrically formed with the fuel hole. ### Claim 6 (depends on 1) The fuel cap integrated aperture type fuel door structure according to claim 1, wherein each of the moving panels have a first end hinge-connected to the fixed ring and a second end hinge-connected to one of the plurality of links. ### Claim 7 (depends on 6) The fuel cap integrated aperture type fuel door structure according to claim 6, wherein the moving panels rotate based on connection parts hinge-connected to the fixed ring, and a plurality of the moving panels are combined with or separated from each other to close or open the fuel hole. ### Claim 8 (depends on 1) The fuel cap integrated aperture type fuel door structure according to claim 1, wherein the rotator ring is provided with a screw thread engaged with an actuator mounted on an outer circumference of the door frame. ### Claim 9 (depends on 1) The fuel cap integrated aperture type fuel door structure according to claim 1, wherein the door frame includes a fuel door cover coupled thereto so that the fixed ring, the rotator ring, and the links are not exposed to an outside. ### Claim 10 (depends on 1) The fuel cap integrated aperture type fuel door structure according to claim 1, wherein the links are arc shaped bars. ### Claim 11 A fuel cap integrated aperture type fuel door structure comprising: a door frame provided with a fuel hole connected to a connection pipe part receiving a fuel introduced from an outside to a vehicle to a fuel tank; a fixed ring fixed to the door frame and concentrically formed with the fuel hole; a rotator ring concentrically formed with the fixed ring and provided in the door frame so as to rotate based on a center of the fuel hole; links hinge-connected to the rotator ring; and moving panels each of which is hinge-connected, at a first end thereof, to a corresponding link and at a second end thereof, to the fixed ring wherein the first end and the second end are spaced from each other and the moving panels are configured to adjust an opened degree of the fuel hole.
