ABSTRACT:
A brake operating device comprising a housing having a bearing portion, an operating lever supported by a pivot on the bearing portion, and a coiled return spring having a pair of engaging portions extending from the axial opposite ends of its coil portion laterally outward for biasing the lever in a returning direction. The coil portion of the spring is accommodated inside the operating lever and has its axis positioned in parallel with the axis of the pivot. One of the engaging portions is attached to the bearing portion, and the other engaging portion extends along the lever and has a slider slidably in contact with the lever inner surface. The spring is therefore retained in position, properly biasing the lever in the returning direction.
