Abstract: A torsional vibration reduction device provided inside a torque converter includes rolling elements, a plate, and a cover. The plate includes rolling chambers housing the rolling elements. The cover encloses and shields the rolling elements and the plate from a working fluid surrounding the torsional vibration reduction device inside the torque converter. The cover includes first and second covers that are joined together with the plate held between the first and second covers. The first and second covers contact the plate in an axial direction of the torque converter at locations that are, with respect to an axis of the torque converter, on an inner peripheral side and on an outer peripheral side of the rolling chambers. Surfaces of the first and second covers are joined to the plate at least at part of the locations where the first and second covers contact the plate.
