Claims

[Scope of utility model registration request]

a first member that is movable relative to the rotational direction and has an input member and an output member that are arranged concentrically;
and a second elastic member that is in surface contact between opposing surfaces of both members, wherein the second elastic member is connected to either the input member or the output member. a convex portion or a concave portion is provided on at least a part of the surface facing the other member, a concave portion or a convex portion is formed on the other member corresponding to the convex portion or the concave portion, and the convex portion By engaging and contacting the input member and the recess, the frictional force between the second elastic member and the input member or the output member is reduced as the input member and the output member move relative to each other. A torque buffer device characterized in that it absorbs fluctuations in torque by changing the torque.
