A torque absorbing disc (A) includes a hub member (1) having a flange portion (12), plate members (2,3) disposed around a hub portion (11) of the hub member (1) so as to be opposite to the flange portion (12) in the axial direction, respectively, a plurality of torsion members (5) elastically connecting between the hub member (1) and the plate members (2,3) in the circumferential direction of the disc (A) and a plurality of seat members (53,54) each of which is disposed among each of the torsion members (5), the plate members (2,3) and the hub member (1). Each seat member (53,54) has one side face portion (21c,31c) contacted with the circumferential end surface of each of the torsion members (5) and the other side face portion contacted with the plate members and the flange portion (12) of the hub member (1). The other face portion is provided with a projected holding portion held on the flange portion (12) of the hub member (1) so as not to be able to move relative to the hub member (1) and a guide portion (53d,54d) nipping the flange portion (12) of the hub member (1) in the axial direction of the disc (A). <MATH> |
