Abstract
Each of a pair of brakes arms has a boss portion formed with a cavity around a pivot on an arm bracket for supporting the brake arms on the body of a bicycle. A pair of return springs for biasing the brake arms toward or away from each other for braking each have a coil portion provided around the pivot and accommodated in the cavity. The return spring has one end fixedly engaged in the boss portion and the other end fixedly engaged in a spring adjusting member which is supported by the pivot and rotatable only in the coil portion winding direction. Thus, each return spring is protected from corrosion, made smoothly operable for the desired braking action and readily adjustable by turning the adjusting member.
