ABSTRACT:
To smooth the response characteristics at a transition point between a first stage and second stage of friction mechanism in a damper disc assembly, the damper disc assembly includes several friction generating mechanisms. One friction generating mechanism 9 includes, a flange 2b, a retaining plate 4, a friction washer 18 and a conical spring 19. A flange 2b has projections 2f projecting toward the retaining plate 4 and extending through a predetermined angle in a circumferential direction. The friction washer 18 is formed with two distinct friction surfaces, disc portion 18a and high frictional coefficient member 18c. The disc portion 18a has a low frictional coefficient and is in contact projections 2f formed on a hub 2 when there is no torsion applied to the damper disc. The high frictional coefficient member 18c is formed at spaced apart intervals on the friction washer 18 and are engagable with the projections 2f in response to torsional vibrations being applied to the damper disc. The second friction washer 18 is coupled with the retaining plate 4 in the circumferential direction. The second conical spring 19 is used to bias the second friction washer 18 toward the flange 2b.
