Abstract
The invention relates to a tank cap for closure of a fuel tank, which can be screwed onto a filler neck and has an inner closure element as well as a cap element and is mounted so as to rotate against the force of a return spring around an angle of free travel that is limited by a first stop and a second stop. The return spring is arranged between the closure element and the cap element so that the longitudinal axis of the return spring lies in a plane that is perpendicular to the axis of rotation of the tank cap.
