Abstract
A torque variation absorbing device for e.g. an automobile engine includes a hysteretic mechanism, a damper mechanism and a torque limiting mechanism which are disposed between two separate, concentric and rotatable inertial bodies. The damper mechanism comprises a plurality of elastic bodies disposed in series between the inertial bodies. A plurality of friction members and a plurality of floating disks are provided between the inertial bodies so that the floating disks may create a very small magnitude of hysteresis through the friction members and act upon at least one of the elastic bodies upon contraction of the latter to absorb any fine variation in torque.
