Abstract
A closure for a fuel tank filler neck has a closure cap which is swivel-mounted on the upper side of the said closure and can be opened from the closed position by the effect of force on a lever arm arranged on the far side of the swivel axis. A pawl for locking and unlocking of the closure cap is swivellable and prestressed in the closing sense or direction by spring force and has an outwardly extending lever arm for mechanically lifting the pawl against the spring force. To ensure a permanent and reliable closing function of the closure cap, the filler neck bears an axially accessible adjusting ring which is arranged coaxially with respect to the cap. The ring is mounted rotatably on the outer circumference of the latter and/or on the axial end face of a shoulder thereof, and has on its upper side, at least in a subregion, a spiral toothing. A toothed segment is arranged on the lever arm of the closure cap. The teeth of the toothed segment are in engagement with the spiral toothing of the ring such that a turning of the adjusting ring has the effect that a force acting in the opening or closing sense can be exerted on the closure cap.
