In a rotary damper, a combination structure between a rotor axis and a rotary member combined with the rotor axis is simplified and ensured. A rotary damper device includes a damper housing internally enclosing a viscous fluid; a rotor including a rotor vane rotatably received inside the damper housing, and a rotor axis provided to project in the rotor vane, and protruding to an outside of the damper housing; and a one-way clutch combined with a protruding end of the rotor axis. The one-way clutch includes an insertion hole through which the protruding end of the rotor axis passes; and a pair of control walls provided to stand in a hole edge on a side facing a damper housing side of the insertion hole in such a way as to be mutually opposed by sandwiching the insertion hole. The protruding end of the rotor axis is heated and deformed in a state wherein the protruding end of the rotor axis has passed through the insertion hole, and protrudes in a radial direction of the rotor axis along a gap between the control walls so as to be engaged with the hole edge of the insertion hole. |
