PROBLEM TO BE SOLVED: To vary the magnitude of torque available during rotation in one direction and that of torque available during rotation in the other direction, regardless of a simple structure. SOLUTION: This rotary damper device comprises a case 10 having a viscous operating fluid Q sealed therein; a rotor 20 provided inside the case 10 in such a way as to be capable of rotating relative thereto; and a movable vane 30 provided on at least either the outer peripheral surface or side face of the rotor 20 and deformed by the viscosity resistance of the operating fluid Q between itself and the case 10 correspondingly to the direction of rotation of the rotor 20 so as to adjust clearance K between the case 10 and itself.
