摘要: A torsional vibration damper that damps torsional vibration effectively in a low-speed range. In the torsional vibration damper, a spring holder is formed by apertures of an input element and an output element, and an elastic member is held in the spring holder. A first moveable range of a planetary element extending from an initial position in a drive direction is wider than a second movable range of the planetary element extending from the initial position in a counter direction.
