<p>An object of this invention is to improve a drum brake device with respect to the brake efficiency, to prevent wear down and deformation of the pivot section between a brake shoe (40) and a pivot lever (50), and to improve the operator's comfort level during braking. For those purposes, this invention provides a drum brake device, wherein a supporting structure (60) for supporting the adjacent ends of the pivot levers (50) is such that the pivot levers may easily follow the brake shoe movement in the drum's rotational direction. <IMAGE></p> |
