<p>PROBLEM TO BE SOLVED: To provide a shoe driving mechanism for a drum brake device capable of improving assembling workability when the mechanism is made into a unit, reducing the number of parts and reducing manufacturing cost. SOLUTION: This shoe driving mechanism 7 is provided with a pair of substrates 25 and 26 fitted and mounted rotatably into/on an anchor pin 11 for a primary shoe, a balance lever 32 and an input lever 34 held between the substrates 25 and 26, an anchor pin 12 for a secondary shoe and first and second lever supporting shafts 28 and 30 having pin functions. The anchor pin 12 for the secondary shoe and the second lever supporting shaft 30 of the first and second lever supporting shafts 28 and 30 are formed into projecting parts molded by pressing of the substrate 26.</p> |
