Abstract
A torsional vibration reducing device includes: a rotating body; an inertial body; a coupling member configured to transmit the torque to the rotating body and to the inertial body; and a first coupling portion and a second coupling portion, which are separately provided to either the rotating body or the inertial body. The first coupling portion engages with the coupling member so as to: restrict movement of the coupling member in a rotational direction of the rotating body; and allow movement of the coupling member in a radial direction of the rotating body. The second coupling portion engages with the coupling member such that when the rotating body and the inertial body rotate relative to each other, a contact portion of the coupling member with respect to the first coupling portion moves in the radial direction of the rotating body.
