The device includes a positioning mechanism for setting the speed change stage of a lever body, a change-over mechanism for changing over the postioning mechanism between an operating position and a non-operating position, and a resistance applying mechanism for applying to the lever body a rotational resistance overcoming a return spring of a derailleur at the non-operating position of the positioning mechanism. The device also includes an adjusting mechanism for adjusting the rotational resistance of the lever body against the return spring of the derailleur.
