Patent ID: 8875847

Claim:
A mechanical brake actuator, comprising: a strut that has two facing plates with a strut-bridge connecting therebetween and that engages with a first brake shoe; a brake lever that engages with a second brake shoe, where said brake lever is retained in a space between said facing plates of the strut and is pivotally supported in the strut at a proximal end thereof, and said brake lever and said strut relatively rotate to spread apart from each other while pulling a brake cable connected to a free end of the brake lever via a connecting pin, and a clip that is attachable to the strut-bridge with a free end thereof in a rotatable manner at a retreat position where the brake cable is connectable to the brake lever via the connecting pin or a progress position where the brake cable is not disconnectable from the brake lever, wherein said clip is initially attached to the strut-bridge at said retreat position, and after the brake cable is connected to the brake lever, said clip is manually rotated so that a folded portion formed on the free end thereof clips on the strut-bridge, ultimately a positioning portion thereof pushing the brake lever when the brake lever is positioned where the brake cable is connectable to the brake lever; therefore, said clip is finally attached to the strut-bridge at said progress position, thereby restricting a rotation of said brake lever in a cable releasing direction.
