Patent ID: 8196713

Claim:
A mechanical type brake actuator, comprising: (a) a strut to engage with one brake shoe, said strut having a pair of facing plates and a bridge connecting said facing plates; and (b) a plate-like brake lever to engage with an other brake shoe and retained in a space between said facing plates of said strut, said brake lever having a proximal portion pivotally supported by said strut, said brake lever and strut rotate relative to each other to spread apart from each other when a brake cable is pulled, said brake cable is connected to a free end of said brake lever via a connecting-pin, characterized in that said mechanical type brake actuator further comprises a retaining member having a tongue with an by-pass hole through which the connecting-pin penetrates and being resiliently deformable toward the free end of said brake lever, only when rotating said brake lever in a cable releasing direction and resiliently deforming the retaining member toward the free end of said brake lever, said connecting-pin is capable of penetrating the by-pass hole of said retaining member to connect said brake cable and the free end of said brake lever, and said connecting-pin movement is restricted after releasing said resilient deformation of said retaining member after connecting said brake cable and said brake lever.
