する間隙自動調整装置。A pair of brake shoes are arranged facing each other on a backing plate, an anchor fixed to the backing plate is sandwiched between one end of the brake shoes, and the other end is rotatably supported by the backing plate. In a cam-type drum brake in which a cam is clamped and both brake shoes are expanded by the rotation of the cam, the anchor is attached to an adjuster case fixed to a backing plate, and the adjuster case is rotatable and movable in the axial direction. An adjuster nut with an adjuster gear formed at one end is screwed onto both sides of the adjuster nut with reverse threads, and the two outer ends are rotated relative to each other at one end of the brake shoe. Consisting of a pair of adjuster screws that are immovably engaged, one end is pivotably supported on a backing plate, one end is engaged with an adjuster gear so that it can be fed in only one direction, and the other end is An automatic gap adjustment device, characterized in that an adjuster lever is provided which abuts and engages a protrusion at the other end of one brake shoe from the outside, and is attached with a return means.
