Abstract
A brake cable mounting structure for a drum brake, in which even if the distance from the brake mounting surface to the center of the brake shoes in the width direction is short, the layout of the brake cable mounting section and the mechanical expander is efficient and effectively provided. Further, the anchor only need to support the braking force, thereby making the device smaller and lighter. The brake cable mounting structure of this invention is characterized in that the inner cable of the brake cable extends out from the brake; and the guide pipe on which the outer casing of the brake cable is integrally fixed with the back plate.
Claims4
A brake cable mounting structure for a drum brake comprising:
- a mechanical expander having an input force portion, said expander disposed adjacent to a pair of adjacent facing ends of brake shoes moveably mounted on a back plate so as to actuate said brake shoes;
- a brake cable having an inner cable connected with said input force portion of said mechanical expander and having an outer casing;
- and
- a guide pipe for guiding said inner cable to pass out of said drum brake, said outer casing being attached to said guide pipe, wherein
- said guide pipe penetrates through a guide pipe insertion hole of said back plate and projects outwardly from a guide pipe fixing portion of said back plate,
- a large diameter overhanging portion provided on an intermediate portion of said guide pipe contacts said back plate at a brake fixing part side,
- a projected outwardly end tip of said guide pipe is formed to be a widened end, and
- said guide pipe is securely fixed on said back plate between said overhanging portion and said widened end.
