Damper device

A damper device comprising:

• a first rotating body including at least a first plate that rotates about a rotation axis, and a second plate that is disposed to face the first plate and rotates integrally with the first plate about the rotation axis;
• a second rotating body that rotates relative to the first rotating body about the rotation axis;
• an elastic mechanical unit that elastically connects the first rotating body and the second rotating body in a rotation direction;
• a control plate including a radially extending portion that extends in a radial direction and is in contact with the elastic mechanical unit, and an axially extending portion that extends in an axial direction and is at least partially accommodated in one of the first rotating body or the second rotating body, the control plate being disposed only in one of a first accommodation space between the first plate and the second rotating body or a second accommodation space between the second plate and the second rotating body in the axial direction;
• a first sliding portion that is disposed between the first rotating body and the control plate, slides with respect to at least one of the first rotating body or the control plate to generate a first sliding torque, has a first opening, and is rotatably supported by an outer peripheral surface of the second rotating body on an inner peripheral surface surrounding the first opening;
• and
• a second sliding portion that is disposed between the second rotating body and the control plate, and slides with respect to at least one of the second rotating body or the control plate to generate a second sliding torque,
• wherein, when the first rotating body and the second rotating body rotate relative to each other, the first sliding torque and the second sliding torque are generated.
