なる、ドラムブレーキの自動調整装置。A brake panel, a wheel cylinder and an anchor block installed on the brake panel, a pair of brake shoes that are expanded and operated by the wheel cylinder using the anchor block as a fulcrum, and these brake shoes are constantly biased in a direction of contraction. In a drum brake equipped with a return spring and a brake drum whose linings are pressed against the inner peripheral surfaces of both brake shoes when they are expanded, one end of a strut is connected to one of the brake shoes, and the other end of the strut is connected to one of the brake shoes. The first arm of a bell crank lever, which is rotatably connected to the wall via a pivot pin, is connected to the other brake shoe with a certain play in the operating direction of the brake shoe. Serrations are carved on the end surface of the second arm, and a removable leaf spring is stretched between the pivot pin and the strut, and the leaf spring is normally engaged with the serrations by the tension of the leaf spring. However, when the pivot pin and the strut generate a relative displacement of a predetermined amount or more in the direction of expansion of both brake shoes against the tension of the leaf spring, they are released from the engaged state with the serrations. An automatic adjustment device for a drum brake, wherein the brake panel or the brake drum is provided with a tool hole into which a tool for removing the spring can be inserted.
