1. A pulley decoupler for an accessory drive, comprising:
an input part;
an output part, the output part and the input part being rotatable about a common axis of rotation and being rotatable to a limited extent relative to one another; and
a centrifugal pendulum device for damping torsional vibrations with a centrifugal pendulum flange which can be rotated about the axis of rotation and which has at least one pendulum mass which is displaceable under centrifugal force relative to the centrifugal pendulum flange, wherein the at least one pendulum mass is acted on by a friction force generated by a first friction device having a first spring and at least one first friction element;
wherein the first spring is supported on a cover of a pulley of the output part.
