Zusammenfassung: | A power transmitting device includes a first rotor and a second rotor rotatably disposed coaxially with a rotational central axis be and in facing relation to each other, a single arc spring that is elastically deformable to a large extent and has a small modulus of elasticity, the arc spring being interposed between the first rotor and the second rotor for urging the first rotor and the second rotor to opposite sides in a ration direction, a first pressing protrusion projecting from the first rotor and a second pressing protrusion projecting from the second rotor, the first pressing protrusion and the second pressing protrusion being disposed in relative positions on superposed rotation trajectories, and a rubber member that is elastically deformable to a small extent and has a large modulus of elasticity, the rubber member being interposed between the first pressing protrusion and the second pressing protrusion with gaps therebetween. |
