Abstract:
A torsional vibration damper having an improved attenuation performance of low frequency vibration. The torsional vibration damper comprises a rotary member rotated by torque, an inertia body rotated relatively on an outer radial side of the rotary member due to torque pulse, and a rolling member coupled to the rotary member and the inertia body. The rotary member includes support sections that are provided on its outer radial side, and by which the rolling member is restricted in a rotating direction of the rotary member and is engaged movably in a radial direction of the rotary member. The inertia body includes: a pair of mass sections respectively projecting toward both sides in an axial direction; and a pair of raceway surfaces on which the rolling member rolls. A center of curvature of each raceway surface is deviated from a rotational center of the rotary member.

Claim (Index 1):
A torsional vibration damper, comprising:\n a rotary member that rotates by being inputted with a torque; an inertia body disposed on an outside in a radial direction of the rotary member so as to rotate freely in a circumferential direction centered on a rotational center axis of the rotary member; and a rolling member that couples the rotary member and the inertia body in a relatively-rotatable manner, wherein torsional vibration of the rotary member is suppressed by relative rotation of the inertia body with respect to the rotary member, the rotary member includes in its outer circumferential section a plurality of support sections by which the rolling member is restricted in a rotating direction of the rotary member and is engaged movably in the radial direction of the rotary member, and the inertia body includes: a pair of mass sections that project toward both sides in a direction of the rotational center axis of the rotary member with respect to the rotary member; and a pair of raceway surfaces that are respectively provided on an inside in the radial direction of the pair of mass sections in a manner enabling the pair of raceway surfaces to be abutted on by the rolling member, the pair of raceway surfaces having a center of curvature in a place deviating from a rotational center of the rotary member.
