A clutch disc assembly (1) is provided with lubrication members (11a, 11b) to reduce the wear of the parts which contact the large coil springs (7) disposed within the clutch disc assembly (1). Plates (4) and (5) and a separated flange (3) are configured to rotate relative to each other. Raised portions (4a) and (5a) of the plates (4) and (5) correspond to a window (3c). Each of the large coil springs (7) extends in a circumferential direction with respect to the clutch disc assembly (1). Each large coil spring is confined within a corresponding the window (3c) of the separated flange (3) and further between the raised portions (4a) and (5a) of the plates (4) and (5). Lubricant-impregnated members (11a, 11b) are provided on a portion of respective sides of the separated flange (3), and are contactable with the large spring coil (7). In one alternate embodiment, a portion of plates (105) and (106) is provided with a plurality of minute apertures (140). The plates (105) and (106) are then provided with a surface hardened layer (130) to reduce wear due to friction.

[ What is claimed:] [1.] A damper disc assembly comprising:a first rotary plate having a first receiving portion, said first rotary plate formed with opposite radially and circumferentially extending surfaces, a portion of each of said extending surfaces radially outward from and adjacent to said first receiving portion being formed with circumferentially extending recesses;a pair of second rotary plates disposed concentrically on either side of said first rotary plate, said second rotary plates being rotatable relative to said first rotary plate and having second receiving portions corresponding to said first receiving portion;an elastic member disposed within said first receiving portion and said second receiving portions elastically coupling the first rotary plate to said second rotary plates in the circumferential direction; anda pair of lubricant-impregnated members disposed in said circumferentially extending recesses such that, in response to centrifugal forces said elastic member contacts said lubricant-impregnated members.
