Abstract
An object of the invention is to provide a rotary damper which can individually control two controlled subjects independently rotatable with each other by utilizing both a viscous resistance by a viscous material and a resistance by a viscous fluid and putting properties thereof to good use. A rotary damper (1A) is provided with first and second chambers (4, 5) which are separated by a partition wall (3), a rotor (6) which is rotatably arranged within the first chamber (4), a viscous material (7) which is filled in a slight gap between the rotor (6) and a slidable contact surface slidably contacted with the rotor (6), a viscous fluid (11) which is filled in the second chamber (5), and a vane (12) which is swingably arranged within the second chamber (5) filled with the viscous fluid (11).
