Abstract: PURPOSE:To improve rigidity and prevent noise generation of a brake in brake shoes of a drum brake without fixing two superposed rims. CONSTITUTION:A brake shoe 20 is composed by superposing an outer shoe 21 (21a, 21b) and an inner shoe 25 (25a, 25b), each having a web and a rim. Absorbing effect of oscillation energy is improved by friction as a whole of the brake shoe 20. The rims 21b, 25b are not fixed to each other and are movable in respect to each other. Thus, they are not so influenced by temporal variation. The outer shoe is made of an iron plate, while the inner shoe 25 is made of cast iron. Rigidity of the outer shoe 21 is thus lowered than that of the inner shoe 25. When the brake is operated, the outer shoe 21 itself is deformed or slid against the inner shoe 25 for keep a close contact condition with the inner shoe 25. Solid friction between the shoes is effectively utilized for improving antivibration effect.
