Abstract:
A drum brake device comprising a brake shoe being movably disposed parallel to a surface on a fixed back plate, a brake lever superposed on a shoe web of the brake shoe, positioned between the back plate and the shoe web, but adjacent to the shoe web, a base end of which is pivotally supported at one end of the shoe web, a shoe-hold mechanism, composed of a shoe-hold pin, rising from the back plate, and a shoe-hold spring, laid on the brake shoe, said shoe-hold pin contracting said shoe-hold spring so as to urge the brake shoe toward the back plate and to hold the brake shoe, and a remote control device which pulls a free end of said brake lever to cause a frictional engagement between the brake shoe and a brake drum, wherein a by-pass hole is formed in said brake lever through which said shoe-hold pin penetrates and a bending section extending toward the back plate is integrally formed at an outermost circumferential edge of said brake lever surrounding the by-pass hole.
