Abstract
A torsional vibration damping device in the drive train of a motor vehicle has two coaxial cover plates which are rotationally connected and are kept at a distance apart. The two coaxial cover plates rotate about a common axis of rotation within a certain angular range relative to a coaxial internally located part arranged between the two cover paltes and the cover plates are elastically connected to the internally located part by a spring element which is effective in the circumferential direction. The cover plates are held apart by distance pieces applied transversely to the circumferential direction. Each distance piece has a joint region where the distance piece is connected to the cover plate and a connecting region which traverses the distance between the cover plates. The radial distance between the joint region and the axis of rotation differs from the radial distance between the connecting region and the axis of rotation.
