とする間隙自動調整装置。A pair of brake shoes are arranged facing each other so as to be expandable on a backing plate fixed to the vehicle body side, and the brake shoes are sandwiched between opposite ends of the backing plate, and the brake shoes are expanded in conjunction with the brake operation. A mechanical leading trailing brake having a cam that opens, has a threaded rod part, a wedge part, and a circular part whose axes coincide with each other, and latch teeth are formed on the outer periphery of the circular part, and the brake is returned to the backing plate. A wedge screw is attached to a pair of links that are screwed together at the threaded rod portion with a stop mechanism, and the other ends of both brake shoes are held in position in the axial direction and connected to the wedge portion, and are fixed to the backing plate. a first adjuster lever whose central portion is rotatably supported by a pin provided with the cam, and whose one end is urged by a return spring to abut against the cam and interlock with the cam; an overtravel spring that is movably wound and has one end locked to a first azimuth lever and a bent portion of the other end elastically engaged with the first azimuth lever so as to be relatively movable; and an overtravel spring. The other end is rotatably supported by a bent portion, and a latch tooth is formed on the side edge of one end, and the latch tooth is attached to a spring so as to mesh with the latch tooth of the wedge screw so as to be able to feed only in one direction. An automatic gap adjustment device characterized by having a near adjuster lever that is biased by the lever.
