Abstract
A torsional vibration reducing device includes a rotating body, and a connection member. The rotating body has a plurality of guide holes. The rotating body includes a plurality of rolling bodies that are accommodated in the plurality of guide holes, respectively. The connection member connects the plurality of rolling bodies such that the plurality of rolling bodies moves integrally in the rotating direction of the rotating body. The connection member is supported so as to be reciprocally swingable in the rotating direction. A first moment that results from a weight of any one of the plurality of rolling bodies and rotates the connection member in a first rotating direction, a second moment that results from a weight of the other of the plurality of rolling bodies and rotates the connection member in a second rotating direction being applied to the connection member.
