Abstract
A damper apparatus according to an embodiment includes a pair of first plates, a second plate, an elastic member, a first friction material and a second friction material. The elastic member is configured to elastically deform in a circumferential direction of a rotation axis by a relative rotation between the pair of first plates and the second plate around the rotation axis. The first friction material is configured to generate a first friction torque in a case where the second plate rotates relative to the pair of first plates in a first direction from an initial state. The second friction material is configured to generate a second friction torque greater than the first friction torque in a case where the second plate rotates relative to the pair of first plates in a second direction which is opposite from the first direction from the initial state.
