Claims

[Scope of utility model registration request]

a back plate, a pair of brake shoes mounted on the back plate and frictionally engaged with the brake drum to provide a braking action; and a pair of brake shoes for pressing the brake shoes against the brake drum when the parking brake is operated. A drum brake comprising a torque lever connected to a parking brake operating means via a cable, comprising a stopper hole bored in the back plate and a stopper member attached to the stopper hole, the stopper hole being , the stopper member is formed of a wide insertion hole and a mounting hole that is continuous with the insertion hole and is narrower than the insertion hole, and the stopper member is a stopper that restricts the return position of the torque lever. , a retaining part that locks into the mounting hole to prevent the stopper member from coming off when the stopper part is inserted into the insertion hole of the stopper hole and slid toward the mounting hole; A drum brake characterized in that the stop part is formed of a fixing part that fixes the stop part in a locked state with the mounting hole part.
