ようにしたことを特徴とするドラムブレーキ。 A disc-shaped bucking plate has a pair of brake shoes arranged facing each other, a return spring that reduces the diameter of both brake shoes, and one brake shoe can swing freely by a spindle on the web. A drum brake comprising: a parking lever that is pivotally supported by the rim of one brake shoe, and whose outer edge abuts the rim of one brake shoe to regulate the brake release position; and a strut that connects the parking lever and the other brake shoe. In the rim of one brake shoe, an inner abutting surface and an outer abutting surface that are connected to each other via a radial step are formed adjacent to each other in the central axis direction, and the parking plate of the buffing plate is A drum brake characterized in that an opening is formed at a position corresponding to the lever, and the outer edge comes into contact with the inner contact surface when normal braking is released.
