PROBLEM TO BE SOLVED: To provide a rotary damper with a multi-layered shaft capable of performing entire assembling operation from one direction and simplifying assembling processes and reducing the number of components and reducing manufacturing costs. SOLUTION: The rotary damper is provided with a bottom at one end and an opening at other end in an axial direction. The rotary damper comprises a casing forming a fluid chamber filled with viscous fluid in its inside, a rotary member comprised of a base housed in the fluid chamber and a shaft extending out of the fluid chamber and relatively rotatable against the casing, and a fluid torque control means controlling existence and scale of torque generated by rotation of the rotary member in cooperation with the base of the rotary member. One or a plurality of partition walls dividing the fluid chamber in the casing into a plurality of fluid sub-chambers and being independent from the casing are provided, and the plurality of the rotary member in which the bases are respectively housed in the plurality of the sub-chambers are provided with a multi-layered shaft structure having relatively coaxial shafts.
