Claims

[Scope of utility model registration request]

A brake shoe disposed so as to be expandable and opposite to a backing plate attached to a vehicle body side, a cam sandwiched between opposite ends of the brake shoe to expand the brake shoe when the brake is operated, and a brake shoe. In a mechanical leading trailing brake having a shoe return spring stretched between one end, the shaft rod provided upright on the backing plate is loosely inserted into the regular shoe with a gap corresponding to the gap, and the shoe return spring returns. A pair of friction clips elastically clamps the center of each web of the brake shoe by applying a frictional force capable of resisting the force, and a support rod that stands between the other end of the brake shoe and stands on the backing plate. An adjuster nut whose outer circumferential surface is a conical surface with a reduced diameter toward the backing plate is screwed together with a multi-thread screw, and the backing plate side has a reduced shape between the adjuster nut and the other end of both brake shoes. An adjuster that includes an anchor block whose one end surface abuts the surface of the adjuster nut and whose other end surface fits into the other end of the brake shoe, and which biases the adjuster nut and anchor block toward the packing plate. An automatic gap adjustment device comprising an anchor-cum-gap adjustment device body provided with a spring and a reset spring.
