Drum brake device with parking brake actuator

摘要

A brake structure that prevents damaging the shoe-hold mechanism by way of securing a larger space at a central region of the brake and achieves a long effective and stable brake function. A by-pass hole 60d, through which the shoe-hold pin 41 is freely penetrating, is formed in the brake lever 60 positioned beneath the shoe web 20b of the brake shoe 20, and the stopper portion 60e contacting the shoe rim 20a is formed on the brake lever 60 so as to avoid the collision between the shoe-hold pin 41 and the by-pass hole 60d when the brake lever 60 is in operation. <IMAGE>
