A dampening disk assembly stabilizes friction generated by friction mechanisms within a first range of torsional angle in a separated hub type of clutch disk assembly. An intermediate member (18, 20) is disposed axially between a clutch plate 31 and a retaining plate 32. The first axial side of the intermediate member is supported by the clutch plate 31. The intermediate member (18, 20) has an intermediate plate 18 and a supporting member or fixing plate 20 with a first part 71 and a supporting portion 73 at an inner circumferential portion. An output hub 3 has a flange 64 disposed axially facing the supporting portion 73. The intermediate member (18, 20) and the hub 3 are axially supported by the clutch plate 31. A first friction mechanism 8 is formed between the fixing plate or supporting member 20 and the retaining plate 32. The first friction mechanism 8 includes a friction washer 81 and a first cone spring 49. A second friction mechanism 10 is formed between the flange 64 of the hub 3 and the supporting portion 73 of the fixing plate 20. The second friction mechanism 10 includes a bushing 19 which connects with the hub 3 in a relatively non-rotatable and axially-movable manner and abuts on the supporting portion 73, and a second cone spring 78 disposed axially between the flange 64 and the bushing 19.
