ABSTRACT:
An operating lever assembly for a bicycle derailleur has a rotor having a rotational resistance greater than the force of a return spring at the derailleur and a lever body freely rotatable, and is provided with a gap at a portion where the rotor is coupled to a lever body, within which gap the lever body is allowed to be freely rotatable, so that the lever body is, when turned or rotated against the return spring force, capable of being returned a certain extent by the force of the derailleur return spring.
