Abstract:
A brake cable connecting apparatus of a brake actuating mechanism for a drum brake, said brake actuating mechanism comprises:a strut engaging with one brake shoe and a brake lever positioned in a space formed between two facing surface walls of said strut and engaging with the other brake shoe; a proximal end of said brake lever is pivotally supported between said two facing surface walls of said strut while a brake cable is connected to a free end of said brake lever by a connecting pin and said brake actuating mechanism moves said brake shoes away from each other as a result of relative rotation of said strut and brake lever about a pivotally supporting point therebetween by operation of said brake cable, wherein a resilient member is provided on a rotating trajection of said brake lever relative to said strut; when said brake lever, at an external position out of said space of said strut where the connecting pin can link the brake cable and the brake lever, rotates and moves in a cable operating direction, either said brake lever or said strut deforms said resilient member to allow the free end of the brake lever to pass into the internal position in said space of the strut thereby securing the linkage of said connecting pin, said brake lever, and said strut, and thus preventing removal of said connecting pin; and when said brake lever at said internal position rotates and moves in a cable releasing direction, either said brake lever or said strut abuts against said resilient member thereby inhibiting said brake lever from rotating in the cable releasing direction.
