Abstract
A torsional vibration reducing apparatus is provided. The torsional vibration reducing apparatus includes a rotating body having a rolling chamber, and a rolling body including a support shaft portion, a first flange portion, a second flange portion, a first corner portion, and a second corner portion. The support shaft portion is housed in the rolling chamber. The flange portions are located respectively at either end of the support shaft portion in an axial direction. A position defined by the support shaft portion and the first flange portion is the first corner portion, and a position defined by the support shaft portion and the second flange portion is the second corner portion. In a section of the rolling body that is along a central axis of the support shaft portion, sectional shapes of the first corner portion and the second corner portion differ from each other.
