Abstract:
A damper unit includes a first damper arranged to transmit a torque around a rotation axis transmitted from an input member side to an output member side, an intermediate member arranged to transmit a torque around the rotation axis transmitted from the first damper to the output member side, and a second damper arranged to transmit a torque around the rotation axis transmitted from the intermediate member to the output member side, wherein at least a portion of the second damper is disposed on a straight line that passes through the first damper and is parallel or substantially parallel to the rotation axis.
