Torque damper device

A torque damper device comprising:

• a first input plate that is formed in a flat plate annular shape and is rotatably driven by a driving force of an engine;
• a second input plate that is formed in a flat plate annular shape, disposed at a position facing the first input plate, and rotatably driven integrally with the first input plate;
• a cylindrical output hub that is disposed coaxially with the first input plate and the second input plate and is rotatably driven by a rotational driving force of the first input plate and the second input plate;
• a flange that is provided between the first input plate and the second input plate projecting radially outward from an outer peripheral surface of the output hub;
• an elastic transmitter that is provided between the first input plate and the second input plate, and the flange, and includes an elastic body that transmits the rotational driving force of the first input plate and the second input plate to the flange;
• a plurality of flat plate annular first friction plates that are provided radially outside the output hub and between the flange and the second input plate;
• a plurality of first intermediate plates that are rotatably driven integrally with the second input plate, formed in a flat plate annular shape, and arranged between the first friction plates;
• and
• a pressure body that is provided between the first input plate and the second input plate and brings the first friction plates and the first intermediate plates into close contact with each other between the flange and the second input plate, wherein
• the output hub comprises:
• a friction plate holder that is formed to have a length equal to or greater than a thickness of the first friction plates and the first intermediate plates that are overlapped with each other in an axial direction on an outer peripheral surface thereof, and is fitted with each of the first friction plates;
• and
• a hub-side fitting portion that is formed to project or be recessed radially in the axial direction on the friction plate holder, and
• the first friction plates each comprise a plate-side fitting portion, that is fitted to the hub-side fitting portion and is formed in a concave or convex shape, on an inner peripheral portion thereof.
