Abstract

In a venting device for a fuel tank (1), a venting line (5) has a movable section (6) and a spring element (14). The free end of the venting line (5) is prestressed against an upper wall of the fuel tank (1). This ensures that a valve (7) which is arranged at the free end of the venting line (5) is always arranged in the vicinity of the upper wall of the fuel tank (1).
