Abstract
A torsional vibration damper in which a mass may be fitted easily into a chamber is provided. In the rotary disc, an insertion hole is formed integrally with the chamber. An opening diameter of the insertion hole is larger than an outer diameter of a flange plate of the mass, and an opening width at a boundary between the insertion hole and the chamber is larger than an outer diameter of a trunk of the mass. The retainer comprises a restricting portion that restricts an oscillating range of the mass in the chamber.
