Abstract
A torque variation absorbing device comprises a driving plate, a flywheel which is rotatable relative to the driving plate through a bearing element in common axis, an elastic member which is disposed in a space defined between the driving plate and the flywheel, an inner peripheral portion of the elastic member secured to either the driving plate or the flywheel, and an outer peripheral surface corresponding to an inner peripheral surface of the other, a plate secured to an outer peripheral surface of the elastic member so as to correspond to the inner peripheral surface, a plurality of rotational members which are rotatably disposed between the plate and the inner peripheral surface in the circumferential direction in such a manner that each rotational member is depressed by the elastic force of the elastic member, and a clearance which is defined between the plate and the inner peripheral surface, and narrows toward both ends of the plate from a center of the plate so as to obtain a large relative angle of torsion and to improve performance during high speed rotation.
