Abstract:
1. A rotary damper comprising: a first rotator configured to rotate about a rotational shaft; a second rotator configured to rotate about the rotational shaft; at least one first viscoelastic body disposed between the first rotator and the second rotator; and a contact member disposed between the first rotator and the second rotator, and configured to apply a compressive load in a rotation direction about the rotational shaft to the at least one first viscoelastic body while being in contact with the at least one first viscoelastic body so that a torque is transmitted between the first rotator and the second rotator, wherein a contact position of the contact member to the at least one first viscoelastic body moves in a radial direction of the rotational shaft.
