する機械式ブレーキ駆動装置。[Claims for Utility Model Registration] A pair of parking spaces whose middle portion is rotatably supported by a fulcrum pin fixed to a bucking plate, and whose one end is locked to a pin fixed to a brake show web. Place the levers facing each other on the parking plate, connect the other ends of both parking levers with a cable, pull the cable holder at the center of the cable, and attach the pair of brake shoes to the drum. In a mechanical brake drive device that generates braking force by pressing against the inner peripheral surface of the cable holder, the cable holder has a pin hole and a cable insertion hole that is convex toward the pin hole and expands from the center toward both ends. A hole is provided, the center part of the cable is inserted into the cable insertion hole, the cable holder support pin protruding from one end of the inner lever is loosely inserted into the pin hole, and the lever fulcrum pin fixed to the other end of the inner lever is pushed out. A mechanical brake drive device, characterized in that it is rotatably supported on a king plate, and the other end of the lever fulcrum pin is coupled to one end of an outer lever.
