PURPOSE: A fuel filler cap structure for multi kinds of vehicles is provided to prevent foreign substances from forming in a retainer ring and to make common use for multi kinds of vehicles possible by improving the structure. CONSTITUTION: A fuel filler cap structure for multi kinds of vehicles comprises a fuel filler cap(20) and a retainer ring(30). The fuel filler cap is coupled to the upper part of a housing(10) for injection of fuel, and the distal end of the outer peripheral surface of the fuel filler cap forms a downward bent-up unit(23). The retainer ring is folded to fix the bent-up unit of the fuel filler cap while covering the bent-up unit of the fuel filler cap. The retainer is coupled with the inner side of the bent-up unit and the retainer ring connects a tether(31) to the fuel filler cap. A fixing protrusion(25) is formed inside the fuel filler cap and the retainer ring is fixed to the fixing protrusion.
