To provide a rotary damper which is suitable as a damper for a brake pedal including a fail-safe function.SOLUTION: In a rotary damper 1 for a brake pedal of a motor vehicle which generates brake torque when a case 11 rotates in a normal rotation direction N relative to a rotor 12, the case 11 is formed by a thermoplastic resin, and a pair of arm parts 19a, 19b, which protrude to the radial outer side and sandwich a plate 5 which rotates around a pedal rotation center O in conjunction with a brake pedal 4, are provided at the case 11. Further, the arm part 19a, which is located at the downstream side in the normal rotation direction N, of the pair of arm parts 19a, 19b is provided with a curved part 191 having a constant width, and the plate 5 is supported by a support part 192 located at the tip side relative to the curved part 191.SELECTED DRAWING: Figure 1

    【課題】フェイルセーフ機能を備えたブレーキペダル用ダンパとして好適なロータリダンパを提供する。【解決手段】ケース11がロータ12に対して正転方向Nに回転すると制動トルクを発生させる、自動車のブレーキペダル用のロータリダンパ1において、ケース11を熱可塑性樹脂で形成するとともに、このケース11に、ブレーキペダル4と連動してペダル回転中心O回りに回転するプレート5を挟む、径方向外方に突出した一対のアーム部19a、19bを設ける。また、一対のアーム部19a、19bのうち、正転方向Nの下流側に位置するアーム部19aに、一定幅の湾曲部191を設けるとともに、この湾曲部191よりも先端側に位置する支持部192でプレート5を支持するようにした。【選択図】図1
