PROBLEM TO BE SOLVED: To provide a rotary damper requiring no viscous fluid. SOLUTION: In a casing C, sliding bodies 8, 9 are incorporated which are moved relatively thereto. Braking grooves 10, 11 are provided in either the casing C or one of the sliding bodies 8, 9, and braking parts 8a, 9a to be slidably fitted into the braking grooves 10, 11 are provided on the other. The braking grooves 10, 11 have tapered faces 10a, 11a formed so that a space between their opposed side faces is gradually narrower in the direction of their depths, and the braking parts 8a, 9a also have tapered faces 8b, 9b opposed to the tapered faces 10a, 11a. On the other hand, a movable body T is provided separately from the sliding bodies 8, 9, on which the rotating force of a rotor 4 operates as thrust. A converting structure is provided for giving pushing force to the braking parts 8a, 9a to make the space between the opposed braking grooves 10, 11 narrower when the thrust operates to move the movable body in the axial direction.
