Provided is a rotary damper on which the timing for generating a damping torque can be set freely. Groove-like bypass passages (805) that are longer in the circumferential direction than vanes (501) are formed in the upper surface (803) of a torque regulation plate (8) arranged on the bottom part (201) of a cylindrical circular chamber (200). When the rotor (5) rotates in a first rotational direction R1, if both end faces (508a, 508b) of the vanes (501) are positioned within a range of the respective bypass passages (805), each area (218) and the corresponding area (217) are communicated via the corresponding bypass passage (805), enabling movement of a viscous fluid (6) from the area (217) to the area (218). Subsequently, if the rotor (5) rotates further in the first rotational direction R1 and one or both of the end faces (508a, 508b) of each vane (501) is outside of the range of the corresponding bypass passage (805), each area (218) and the corresponding area (217) are not communicated via the corresponding bypass passage (805), and the viscous fluid (6) is unable to move from each area (217) to the corresponding area (218).
