ラムブレーキの制動間隙自動調整装置。 One end of a pair of brake shoes slidably supported on a back plate is in contact with an anchor to serve as a fulcrum, and the other end is arranged so as to be expandable by a brake shoe expansion device, and the brake shoe can be expanded. Both ends of the strut are brought into contact with a shoe web near the device, and the adjustment gear of this strut is rotated by an adjustment lever rotatably provided on the shoe web to extend the strut and move the return positions of both brake shoes outward. In the drum brake automatic braking gap adjustment device that automatically adjusts the braking gap by changing the braking gap, the adjustment lever includes a first arm having a feed pawl that engages with an adjustment gear at its tip, and an end of the strut. A second arm that contacts and restricts rotation and a spring leg extending from the first arm are integrally formed, and
The drum brake is characterized in that the spring leg portion is disposed in resilient engagement with the brake shoe web so as to rotate the feed pawl in the direction of engagement with the adjustment gear and the adjustment gear in the direction of strut extension. Brake gap automatic adjustment device.
