Abstract: Provided is a torque damper device capable of setting high hysteresis in a wide range and improving assembling property and maintainability of a high friction material for generating the high hysteresis. A torque damper device 100 includes an output hub 104 and a flange 107 between a first input plate 101 and a second input plate 102 rotatably driven by a rotational driving force of an engine. The output hub 104 is formed in a cylindrical shape. The flange 107 is attached to a portion that projects radially outward of the output hub 104. Further, the output hub 104 is formed with a friction plate holder 106 on an outer peripheral surface thereof. The friction plate holder 106 is fitted to a plate-side fitting portion 111a of a first friction plate 111, and is formed to have an axial length longer than a total thickness of the first friction plate 111 and a first intermediate plate 112.
