A fuel filling device includes a fuel pipe seat having a filling port and a fuel pipe in communication with the filling port. Three engagement portions are formed on an inner peripheral face of the fuel pipe. A fuel cap includes a body and an operative portion mounted to the body. Three tracks are formed on an outer periphery of the body. Each track includes a front, lower end and a rear, higher end having a stop. An entrance is defined in front of the front, lower end of each track. The fuel cap is inserted into the fuel pipe with the engagement portions respectively received in the entrances of the tracks. The fuel cap is rotated in a locking direction. The tracks move relative to the engagement portions until the engagement portions are stopped by the stops of the tracks, and the fuel cap is in a locking position.
