Torsional vibration damper

A torsional vibration damper is configured with a drive-side transmission element (5) and an output-side transmission element (9) which can be deflected in a rotational manner coaxially with respect to the former and is connected to the drive-side transmission element via a damping device (7) which is provided with energy stores (28) and in which the energy stores are supported on sliding elements (25, 30, 35) which are arranged in one of the transmission elements such that they can move in the circumferential direction, and which have circumferential projections (62), which are directed to in each case adjacent sliding elements, for the energy stores and/or penetration spaces (66) for circumferential projections which are provided on the respectively adjacent sliding element, wherein, in the axial direction on their circumferential side which in each case faces an adjacent sliding element in the circumferential direction, the sliding elements have at least one circumferential projection and/or at least one p
