Abstract
In a torsional vibration reducing device, a protrusion projecting radially outward of the rotating body is formed on an inner wall surface. The protrusion is formed on a rotation direction side of a rotating body relative to a straight line passing through a rotation center of the rotating body and a center of a rolling element when the rolling element is located in a middle between both end positions to which the rolling element swings within the roller chamber, and while the rolling element is located at an end portion of a roller chamber on the rotation direction side of the rotating body, a gap is equal to or less than a predetermined value between the rolling element and a wall surface of the roller chamber on a straight line passing through a rotation center of the rotating body and a tip of the protrusion.
