DAMPER DEVICE

A damper device for transmitting power to an output-side member is disclosed. The damper device includes input-side and output-side rotors, a plurality of elastic members, and a hysteresis generating mechanism. The input-side rotor, to which power is inputted, is rotatable. The output-side rotor is rotatable relative to the input-side rotor. The output-side rotor includes a hub and a plurality of flanges. The hub is coupled to the output-side member. The plurality of flanges extend radially outward from the hub. The plurality of flanges are disposed at predetermined intervals in a circumferential direction. The plurality of elastic members are disposed circumferentially between the plurality of flanges, and elastically couple the input-side rotor and the output-side rotor in the circumferential direction. The hysteresis generating mechanism is disposed axially between the input-side rotor and the plurality of flanges, and configured to generate a hysteresis torque between the input-side rotor and the output-side rotor.
