A rotary damper, in particular for actuated parts in automotive vehicles, comprising a housing including a cylindrical damper chamber, a liquid in the chamber, a rotatably supported shaft in the chamber having at least one vane such that upon rotation of the shaft displaced liquid flows through a flow constriction between the vane and the wall of the chamber, characterized in that the vane is inclined relative to the shaft in the circumferential direction of the shaft and relative to a diameter extending through the base of the vane, and that the vane is adapted to swing relative to the shaft such that upon a rotation of the shaft in one sense the vane is moved towards the chamber wall and upon rotation in the opposite sense the vane is moved towards the shaft.
