Abstract

PURPOSE: To attempt size reduction etc of such a device as pushing brake shoes to a brake drum by turning cams, through those processes of integrating cam shafts with levers to turn the cam shafts and constructing the cams and the cam shafts separately.
CONSTITUTION: A pair of brake shoes 6 provided inside a brake drum 5 with convenience of free engagement and disengagement are pivotted on a lid member 4 by a pivot 7 at their one side ends and respectively caught by cams 8 at their other side ends. Each cam 8 is provided with a curved cam face 8a with an opening 8b between its partially flattened parts 8c, and connected to a cam shaft 9 through serration fitting. Each cam shaft 9 is provided with a flat part 9b formed by gaining a part facing to the opening 8b of the cam 8, and a lever 12 is firmly integrated with the end of the cam shaft 9 projected from the lid member 4. Wen two levers 12 are turned in one body by the drawing work of an unillustrated wire, brake shoes 6 are expanded by cams 8 and pushed to the brake drum 5 for generating a braking power.
