ABSTRACT:
A clutch disc has at least two kinds of torsion damper springs arranged circumferentially around a hub of the clutch disc. First damper springs have a spring constant smaller than that of second damper springs. The first springs and the second springs are not arranged in series, end to end, in a circle, but the first springs are arranged in parallel with the second springs. The first springs are wound around an annular wire guide concentric with the hub. In one embodiment, the annular wire guide extends through the second springs, and the first springs are inserted in the second springs, respectively. In another embodiment, the annular wire guide is mounted on the outer periphery of a flange of the hub outside the second springs.
