A viscous fluid is contained in a space, and the inner periphery of the outer cylindrical wall of the dish-shaped housing holds a peripheral edge of the flange of the cap that is pushed into the space surrounded by the outer cylindrical wall from above. holding claws are provided in the circumferential direction to prevent the cap from escaping upward, and the lower surface of the flange of the cap held by the holding claws is brought into contact with the upper surface of the brake plate portion of the rotor via the viscous fluid. Features a rotating damper. (2) In the rotary damper according to claim 1, a hole is formed in the circular bottom wall of the dish-shaped housing directly below the holding claw, and the holding claw is formed with the mold that passes through the hole. A rotary damper characterized in that, by doing so, the engagement distance for the holding claws to protrude inward from the inner periphery of the outer circumferential cylinder wall is increased. (3) In the rotary damper according to claim 1, by holding the flange of the cap with the retaining claws on the inner periphery of the outer cylindrical wall of the dish-shaped housing, the inner periphery of the cap-shaped part is attached to the cap. A rotary damper characterized in that a small diameter O-ring is pressed around the rotating shaft of a rotor.
