1. A damper device comprising:
a first rotary body that includes at least a first plate that is rotatable about a rotational axis and a second plate that is disposed to face the first plate and that is rotatable about the rotational axis together with the first plate;
a second rotary body that is rotatable relative to the first rotary body about the rotational axis;
an elastic mechanism portion that elastically couples the first rotary body and the second rotary body to each other in a rotational direction;
a control plate that includes a radially extending portion that extends in a radial direction to abut against the elastic mechanism portion and an axially extending portion that extends in an axial direction to be at least partially housed in one of the first rotary body and the second rotary body, the control plate being disposed in only one of a first housing space between the first plate and the second rotary body and a second housing space between the second plate and the second rotary body in the axial direction;
a first sliding portion that is disposed between the first rotary body and the control plate and that is slid with respect to at least one of the first rotary body and the control plate to generate first sliding torque; and
a second sliding portion that is disposed between the second rotary body and the control plate and that is slid with respect to at least one of the second rotary body and the control plate to generate second sliding torque, wherein
the first sliding torque and the second sliding torque are generated when the first rotary body and the second rotary body are rotated relative to each other, and
one of the first sliding torque and the second sliding torque is larger than the other, and is generated only when the first rotary body and the second rotary body are rotated relative to each other in only one direction.
