PROBLEM TO BE SOLVED: To receive restriction on the size of an elastic body, such as deformation or buckling of the elastic body due to centrifugal force with enlargement of the elastic body, if the elastic body absorbing torsional vibration is included in a rotation system, in a torsional damper.SOLUTION: A torsional damper 10 includes a planetary gear mechanism 12. One of a sun gear 18, a carrier 20 and a ring gear 22 of the planetary gear mechanism 12 is connected to an input shaft, another one is connected to an output shaft, and the other one is connected to one ends of elastic bodies 14A, 14B of which the other ends are fixed.SELECTED DRAWING: Figure 1 |
