A torsional vibration damping device ( 1 ), in particular for a motor vehicle clutch, said device comprising a disc ( 60 ) and a support ( 80 ) mounted mobile in rotation relative to each other about a common main axis, and linked in rotation via circumferential elastic members ( 90 ) damping torsional vibrations, said elastic members being interposed between the disc ( 60 ) and the support ( 80 ) and maintained in position circumferentially via lugs ( 65 ) of the disc ( 60 ) and lugs ( 82,84 ) of the support ( 80 ) whereon are supported the elastic members ( 90 ) and radially via a guide ring ( 100 ) passing through the elastic members ( 90 ) and integral with the disc ( 60 ). Said device is characterised in that the lugs ( 82,84 ) of the support ( 80 ) are mounted on either side of a section of the ring ( 100 ) and the lugs ( 65 ) of the disc ( 60 ) can move freely at the angle between the lugs ( 82,84 ) of the support ( 80 ).
