Abstract: A rotary damper includes a cylindrical member having walls on an inner peripheral surface of a cylindrical chamber along a radial line, and a rotor member having vanes moving along the inner peripheral surface of the cylindrical chamber. A resistance force of a viscous fluid filled in the cylindrical chamber is applied to the vanes when the cylindrical member rotates relative to the rotor member. The rotor member is formed of a thermoplastic resin containing inorganic filler or fiber. Thus, the rotor member having high strength can be obtained.
