PROBLEM TO BE SOLVED: To improve a rotation moderator so as to obtain precise braking torque. SOLUTION: This rotation moderator comprises a stator 2, a rotor 5, 7, 8, an elastic element 3, and a rolling members 4, When the rotor 5, 7, 8, carries out a rotational movement to be moderated with respect to the stator 2, balls 4 are driven by the rotor 5, 7, 8 while remaining partially embedded in the elastic element 3. The elastic element 3 has a wall 16 parallel to end walls 10A, 10B of the stator 2, in which the balls 4 penetrate. |
