Abstract
A damper mechanism or a damper disk assembly realizing a low rigidity using a pair of elastic members is provided to achieve a further low rigidity in a region with small torques. The damper mechanism has a drive member, a driven member, a pair of first torsion springsA andB, and a second torsion spring. The springsA andB are functionally provided in series with each other in a rotational direction. The springis functionally provided in parallel with the springsA andB in such a way that the springis compressed in the rotational direction after the springsA andB are compressed to a certain angle when the drive memberand the driven memberrotate relative to each other.
