A fuel tank cap adapted to be installed to a vehicle body that has a fuel tank opening and a cap installation portion, said fuel tank cap comprising:
- a seal cap unit including a locking cap body that has
- a handheld wall, and
- a surrounding wall extending from a periphery of said handheld wall, adapted to removably and sealingly cover the fuel tank opening, and formed with an engaging groove that extends annularly along an outer surface of said surrounding wall;
- and
- a detaching-proof unit including
- a ring sleeve member that has
- an outer ring wall surrounding said surrounding wall, and
- a resilient wall extending obliquely from an end of said outer ring wall adjacent to said handheld wall, and engaged resiliently with said engaging groove, and
- a connection member that is connected to said ring sleeve member and that is configured to be connected to the cap installation portion of the vehicle body;
- wherein said surrounding wall of said locking cap body has
- an annular wall portion,
- a flange portion that projects outwardly around a side of said annular wall portion adjacent to said handheld wall, and
- a hook portion that projects outwardly from a side of said annular wall portion distal from said handheld wall;
- wherein said annular wall portion, said flange portion, and said hook portion cooperatively define said engaging groove;
- wherein said flange portion abuts against said end of said outer ring wall that is adjacent to said handheld wall;
- and
- wherein said hook portion abuts against an end of said resilient wall that is distal from said end of said outer ring wall that is adjacent to said handheld wall.
