動調整装置。[Claims for Utility Model Registration] An automatic shoe operation gap adjustment device for a drum brake in which a pair of brake shoes are pressed against a brake drum by pushing out a piston fitted to a cylinder body, the device comprising: Engagement teeth are provided rotatably around one axis on a member integral with the body, and are arc-shaped around the axis, and formed along a pitch line in which the radius of curvature becomes larger as it progresses in one circumferential direction. an adjusting member that is fixed to the piston and that engages with the acting portion when the piston is pushed out by a predetermined amount or more to cause the adjustment member to The adjusting member is rotated in the positive direction, and is provided with a pawl member that engages with a gold tooth disposed at the front of the engaging member that engages with the operating portion when the piston is returned by the predetermined amount from the extrusion end. 1. An automatic shoe operation gap adjustment device for a drum brake, comprising a locking mechanism that allows rotation in one direction and prevents rotation in the opposite direction.
