A Torsion damper wherein a first group of friction rings is supported in circumferential direction so as to be stationary with respect to the torque output part, and a second group of friction rings is supported in circumferential direction in the first swivel angle range so as to be moveable relative to the torque input disk and torque output disk, and in the second swivel angle range the second group of friction rings is supported in circumferential direction in a driving connection with respect to the torque input disk and executes a synchronous rotational movement with the torque input disk, wherein in the second swivel angle range a relative movement in circumferential direction takes place between the torque output disk and the second friction ring group, and a relative movement in circumferential direction takes place between the torque input disk and the first friction ring group.
