Abstract
A power transmitting device includes a first rotor and a second rotor rotatably disposed coaxially with a rotational central axis and in facing relation to each other. A first pressing protrusion projecting from the first rotor and a second pressing protrusion projecting from the second rotor are disposed in relative positions on superposed rotation trajectories. A soft rubber member elastically deformable to a large extent and has a small modulus of elasticity and a hard rubber member elastically deformable to a small extent and has a large modulus of elasticity are interposed between the first and second pressing protrusions. While no relative torque load is being applied to the first and second rotors, the soft rubber member is held in contact with both the first and second pressing protrusions, and the hard rubber member is interposed between the first pressing protrusion and the second pressing protrusion with gaps therebetween.
