PROBLEM TO BE SOLVED: To provide a torsional rubber damper having high durability, and capable of being miniaturized and easily manufactured with high vibration resistance.SOLUTION: A first inertia mass member 121 has an annular first holding portion 1211 opposed to at least a part in a radial direction as a radiation direction vertical to a rotating shaft of a first face 111 as one face of a hub plate 11, and a first connecting portion 1212 disposed on an outer diameter-side end portion of the first holding portion 1211. A second inertia mass member 122 has an annular second holding portion 1221 opposed to at least a part of a radial direction of a second face 112 as a back face of the first face 111 of the hub plate 11, and a second connecting portion 1222 disposed on an outer diameter-side end portion of the second holding portion 1221. The first connecting portion 1212 and the second connecting portion 1222 are fastened by fitting or welding. A first elastic member 13 is compressed and held between the first face 111 of the hub plate 11 and the first holding portion 1211 of the first inertia mass member 121.SELECTED DRAWING: Figure 2 |
