Abstract
A torque fluctuation absorbing apparatus includes a hub member with a flange portion, first and second side-plates provided at both axial sides of the flange portion, respectively, a damper mechanism absorbing a fluctuation of a relative torque generated between the flange portion of the hub member and the first and second side-plates, a thrust member provided between the first side-plate and the flange portion of the hub member, and a first disc spring provided between the first side-plate and the thrust member and biasing the thrust member towards the flange portion of the hub member. The first side plate includes a bent portion bent towards the flange portion of the hub member and a bore formed at the bent portion, and the thrust member is formed with an engagement portion extending through the bore of the first side-plate and engaged with the bore of the first side-plate.
