Disk brake device

Abstract: A disk brake device comprises a brake lever (3A) toward which a tilting force is applied in opening operation. This brake lever (3A) is formed at its lower end with an outwardly protruding stopper (58) into which an adjusting bolt (56) is screwed vertically. A base seat (59) is provided on a base plate (1) immediately under the stopper (58). A pinion (61) is fitted over an upper end of the adjusting bolt (56) via a one-way clutch (60) so as to rotate the adjusting bolt (56) only in a direction of fasting the same downward. A rack (67), which is supported by the base plate (1), is meshed with the pinion (61) to have a predetermined backlash and to extend in a direction of swing of the brake levers (3A,3B). This disk brake device allows to assuredly maintain the brake levers (3A,3B) at equally opened positions at left and right in a brake releasing condition, even if brake linings (9A,9B) are worn out and adjustment is made by an automatic lining wear adjusting unit (53) to automatically decrease the gap caused by wear of the brake linings (9A,9B).
