Power transmitting device

A power transmitting device comprising:

• a first rotor and a second rotor that are 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, the first pressing protrusion and the second pressing protrusion being disposed in relative positions on superposed rotation trajectories;
• and
• a soft rubber member that is elastically deformable to a large extent and has a small modulus of elasticity and a hard rubber member that is elastically deformable to a small extent and has a large modulus of elasticity, the soft rubber member and the hard rubber member being interposed between the first pressing protrusion and the second pressing protrusion;
• wherein while no relative torque load is being applied to the first rotor and the second rotor;
• the soft rubber member is held in contact with both the first pressing protrusion and the second pressing protrusion;
• the hard rubber member is interposed between the first pressing protrusion and
• the second pressing protrusion with gaps therebetween, and
• the soft rubber member and the hard rubber member are integrally formed with each other by being connected by a connecting rubber web.
