Abstract:
A torsional vibration damper in which vibration damping performance is ensured by preventing a contact between a rolling mass and a rotary member. A rolling mass includes a trunk penetrating through a bore. A first corner formed in an axial end of the trunk is rounded. A rotary member includes a second corner formed in the bore. an axial length of the first corner of the rolling mass is longer than an axial length of the second corner of the rotary member.

Claim (Index 1):
A torsional vibration damper comprising:\n a rotary member that is rotated by a torque; a bore that is formed on the rotary member; and a rolling mass that is oscillated along a raceway surface of the bore by a rotation of the rotary member; wherein the rolling mass includes a trunk penetrating through the bore, a first corner formed in any one of an axial end of the trunk in which an outer diameter of the trunk increases gradually toward an axial end, and a flange portion formed on axially outer side of the first corner whose outer diameter is larger than an opening width of the bore, the rotary member includes a second corner formed in the bore in which an opening width of the bore increases gradually toward a radially outer side, the second corner includes a radially outer corner at which a thickness of the rotary member is maximum thickness, the first corner includes an opposing point that is to be opposed to the radially outer corner of the rotary member in an axial direction when the rolling mass is oscillated along a raceway surface of the bore, and an axial length between a starting point of the first corner and the opposing point in the rolling mass is longer than an axial length of the second corner in the rotary member.
