A mechanical brake actuator realizing the miniaturization of the entire device and the reduction of the parts costs is provided. When the brake lever rotates in the cable releasing direction, the connecting pin can be connected with the free end of the brake lever from one facing plate side while the other facing plate restricts the movement of the connecting pin, and the clip (30) is set on one facing plate (23b) so as to restrict the movement of the connecting pin after connecting the brake cable and the brake lever via the connecting pin.

I claim: 1. A mechanical brake actuator comprising: (a) a strut to engage with one brake shoe, said strut including first and second facing plates and a bridge portion connecting said facing plates; and (b) a plate-like brake lever to engage with the other brake shoe and to be retained in a space between said facing plates of said strut, said brake lever including a proximal end pivotally supported at said strut, said brake lever and strut relatively rotate to spread apart from each other as pulling a brake cable connected to a free end of said brake lever via a connecting pin, wherein said first facing plate is designed so as to permit a longitudinal movement of said connecting pin to connect said brake cable and the free end of said brake lever while the brake lever rotates in a cable releasing direction to a limit, and said second facing plate is designed so as to restrict the longitudinal movement of said connecting pin while said brake lever rotates in said cable releasing direction to said limit, and a clip is set on said first facing plate so as to restrict the longitudinal movement of said connecting pin which connects said brake cable and the brake lever. 2. The mechanical brake actuator according to claim 1, wherein a notched groove is formed on said first facing plate to permit said longitudinal movement of said connecting pin therethrough while said brake lever rotates in said cable releasing direction to said limit. 3. The mechanical brake actuator according to claim 1, wherein a means to restrict a lateral movement of said clip is provided on said first facing plate. 4. The mechanical brake actuator according to claim 1, wherein said clip is temporarily set on said first facing plate so as not to separate each other. 5. The mechanical brake actuator according to claim 1, wherein said clip is slidably set on said first facing plate. 6. The mechanical brake actuator according to claim 1, wherein said clip is rotatably set on said first facing plate.
