An operating force transmission device for a brake which transmits an input operating force applied to a brake lever to operating members of the brake through a control cable formed of an inner wire disposed within an outer sheath and interconnecting the brake. The device includes a housing, a receiving member supported movably relative to the housing and adapted to retain thereto one of the inner wire and the outer sheath of the control cable. A control spring is provided for deflecting in response to a braking force output of the operating members of the brake in excess of a predetermined magnitude to enable the receiving member to move relative to the housing when the predetermined braking force output magnitude is exceeded. This reduces the magnitude of a further braking force output of the operating members of the brake with respect to the magnitude of the input operating force applied to the brake lever and transmitted to the operating members of the brake. An adjuster is provided to adjust the spring force of the control spring to change the predetermined braking force output magnitude at which the control spring deflects to enable the receiving member to move relative to the housing.

An operating force transmission device for a brake, for transmitting an input operating force applied to a brake lever to braking members of the brake through a control cable interconnecting the brake lever and the brake, the control cable comprising an inner wire disposed within an outer sheath, said device comprising: a housing; a receiving member supported movably relative to said housing and being adapted to retain thereto one of the inner wire and the outer sheath of the control cable; a control spring means for deflecting responsive to a braking force output provided by the braking members of the brake exceeding a predetermined magnitude, to enable said receiving member to move relative to said housing when said predetermined braking force magnitude is exceeded so as to reduce a magnitude of a further braking force output of the braking members of the brake with respect to a magnitude of the input operating force supplied to the brake lever and transmitted to the braking members of the brake; an adjuster means for adjusting a spring force of said control spring means to change said predetermined magnitude of said braking force output at which said control spring means deflects to enable said receiving member to move relative to said housing; a stopper means for impeding movement of said receiving member relative to said housing in excess of a predetermined amount, said stopper means being provided between said housing and said receiving member and including a stopper having a plurality of impeding positions for impeding movement of said receiving member with respect to said housing; and a selection means for causing said receiving member to selectively engage with said impeding positions.
