A rotary damper includes an electromagnetic damper motor, a damper housing surrounding the damper motor and configured as tubular torsion spring secured by a fastening element to a first mass. A lever is swingably mounted relative to the fastening element and connected to a second mass. The torsion spring is connected with one end to the fastening element and with another end to the lever. A gear mechanism formed as strain wave gearing transmits and/or modifies a relative rotational movement between the first and second masses to the damper motor for vibration damping. The strain wave gearing includes a rigid unit having internal teeth, a flexible unit having external teeth, and an oval wave generator rotatably mounted in the flexible unit and causing a deformation of the flexible unit, when rotating, with the rigid and flexible units coupled to one another by a formfit via the internal and external teeth.
