The torque variation absorbing device comprises a driving plate, a flywheel, and a spring mechanism, a damping and torque limiting mechanism and a hysteresis mechanism installed between the driving plate and the flywheel. The flywheel is divided into a flywheel body and a driven plate which are connected together by a bolt screwed into a bolt hole in the flywheel body and the driven plate. The bolt hole provided in the driven plate extends through the driven plate up to a sliding friction plane between the hysteresis mechanism and the driven plate. The dust generated by the friction of the hysteresis mechanism can be collected into the bolt hole.
