A clutch disc assembly (1) is provided a lubrication member (11) to suppress the wear of parts which contact any of the 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) is confined within the window (3c), the raised portions (4a) and (5a) of the plates (4) and (5) and the separated flange (3) in the circumferential direction. A lubricant-impregnated member (11) is provided in the plates (4) and (5), and is contactable with the large spring coil (7).
