Abstract: In a drum brake apparatus, a mount bracket to be attached to a vehicle body includes a first flange part which protrudes from a central cylindrical part outwardly in the radial direction of a drive shaft and fixes an anchor pin thereto, and a second flange part formed by extending a part of a peripheral edge of the first flange part more outwardly in the radial direction of the drive shaft. The protruding direction of the first flange part from a center of the cylindrical part and the protruding direction of the second flange part from the center of the cylindrical part are substantially the same. An imaginary line going through the center of the cylindrical part and the anchor pin passes through a point between two of a plurality of attachment holes of the second flange part.
