Provided is a rotary damper (1) suitable for use as a damper for a brake pedal with a fail-safe feature. In the rotary damper (1) intended for a brake pedal of an automobile and configured to generate a damping torque by rotation of a casing (11) in a forward direction N relative a rotor (12), the casing (11) is made of thermoplastic resin and is provided with a pair of arms (19a, 19b) projecting radially outward so as to hold a plate (5) therebetween. The plate (5) is configured to rotate about a pedal rotation center in conjunction with the brake pedal (4). Moreover, the arm (19a) out of the arms (19a, 19b), which is located downstream in the forward direction, includes a curved portion (191) with a constant width and a supporting portion (192) located more distal than the curved portion (191) is, and is configured to support the plate (5) with the supporting portion (192).
A rotary damper for a brake pedal of an automobile, the rotary damper comprising a rotor and a casing containing the rotor inside to allow relative rotation between the casing and the rotor, and being configured to generate a damping torque by rotating the casing in a forward direction relative to the rotor, wherein
