Damper apparatus

A damper apparatus comprising:

• a pair of first plates arranged at a position where the pair of first plates is away from each other in an axial direction of a rotation axis, the pair of first plates being configured to be rotatable around the rotation axis in a state where the pair of first plates intersects with the rotation axis;
• a second plate including a portion which is positioned at an inner side of the pair of first plates and configured to be rotatable around the rotation axis in a state where the second plate intersects with the rotation axis;
• an elastic member elastically deforming in a circumferential direction of the rotation axis by a relative rotation between the pair of first plates and the second plate around the rotation axis;
• a first friction material generating a first friction torque in a case where the second plate rotates relative to the pair of first plates in a first direction;
• a second friction material generating 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;
• a third plate arranged between the first friction material and the second friction material and configured to be rotatable around the rotation axis in a state where the third plate intersects with the rotation axis;
• the second plate and the third plate being inhibited from integrally rotating with each other and the first friction torque being generated by a friction of the first friction material when the second plate rotates relative to the pair of first plates in the first direction;
• and
• the second plate and the third plate integrally rotating with each other and the second friction torque being generated by a friction of the second friction material when the second plate rotates relative to the pair of first plates in the second direction.
