Fuel door apparatus for vehicle

A fuel door apparatus for a vehicle, comprising:

• a fuel door rotatable connected to a door housing, wherein the fuel door is connected with an elastic member of the door housing to receive an elastic force in an opening direction and includes a guide pin elastically moving;
• a locking lever rotatably connected to the door housing, wherein the locking lever has a first end portion disposed on a rotation radius of the guide pin, such that the guide pin passes by the locking lever along the rotation radius when the fuel door rotates from an opening position to a closed position, and the locking lever rotates with the guide pin when the fuel door rotates from the closed position to the opening position;
• a restraining lever spaced apart from the locking lever to be rotatable on the door housing, wherein the restraining lever has a first end portion disposed in a radius, on which a second end portion of the locking lever rotates, and is latched on the locking lever in the closed position;
• and
• a drive controller disposed in the door housing, wherein the driver controller is in contact with or separated from the restraining lever depending on whether the fuel door is opened or closed to selectively allow rotation of the restraining lever.
