Torque absorbing device

摘要

A torque absorbing device includes a hub member having a flange portion, plate members disposed around a hub portion of the hub member so as to be positioned opposite the flange portion in the axial direction, a plurality of torsion members elastically interconnecting the hub member and the plate members in the circumferential direction of the disc, and a plurality of seat members each of which is disposed among each of the torsion members, the plate members and the hub member. Each seat member has one side face portion contacting the circumferential end surface of each of the torsion members and the other side face portion contacting the plate members and the flange portion of the hub member. The other face portion is provided with a projected holding portion held on the flange portion of the hub member so as not to be able to move relative to the hub member and a guide portion nipping the flange portion of the hub member in the axial direction of the disc.
