  "textContent": "A flap device for a motor vehicle comprises a flap housing that can be flowed through by a gas flow; and a flap shaft that is rotatably supported about an axis of rotation in the flap housing by means of at least a first and a second bearing element, which are held at the flap housing, and that carries a flap for selectively blocking or throttling the gas flow. The flap shaft is supported at the first bearing element in a first axial direction via a fixed abutment element that is axially fixedly arranged with respect to the flap shaft. The flap shaft is supported at the second bearing element in a second axial direction, which is oriented opposite the first axial direction, via a movable abutment element that is axially displaceably seated on the flap shaft, with the movable abutment element being preloaded in a direction toward the second bearing element by means of a spring device, and with the spring device in this respect being supported at a support surface fixed to the shaft and thus pressing the fixed abutment element against the first bearing element.",
