1. An eccentric gear unit for a braking force generator, comprising:
an input shaft having an eccentric, the input shaft being rotatable about an axis of rotation;
an output shaft that is coaxial with the input shaft
a ring gear;
a cam that is arranged to roll on the ring gear and that includes at least one opening;
wherein:
the eccentric is mounted in a central hole of the cam;
the cam is coupled to the output shaft via a coupling arrangement which includes at least one pin that each engages with the cam by extending in a respective one of the at least one opening of the cam; and
the eccentric gear unit includes at least one of the following features (I)-(II):
(I) a respective interior surface of each of one or more of the at least one opening extends perimeter-wise with a non-circular shape around a respective one of the at least one pin; and
(II) a respective exterior surface of each of one or more of the at least one pin, which faces a respective interior surface of a respective one of the at least one opening, extends perimeter-wise within the respective one of the at least one opening with a non-circular shape.
