Claims

[Scope of utility model registration request]

It has a drive plate connected to a drive shaft, a flywheel coaxially provided with the drive plate and rotatable relative to the drive plate, and has a coil spring and spring seats at both ends of the coil spring. In the torque fluctuation absorbing device configured by interposing a spring mechanism and a damping/torque limit mechanism having a driven disk in contact with the spring seat between the drive plate and the flywheel, the driven disk may . A torque fluctuation absorbing device, characterized in that an engagement surface with the spring seat is formed into a concave shape so as to be aligned with the spring seat.
