To provide a multiple disk brush which has a sound monolithic structure of a number of disk brushes.

The multiple disk brush 15 has a monolithic structure of a number of coaxial disk brushes 7, which are formed by providing a number of brush-planting holes 2 spaced from each other on the peripheral edge of a disk 1, inserting bristle tufts 3 into the brush-planting holes 2 and folding the same into two over the outer edge of the brush-planting holes 2, tying the base portions of the twofold bristle tufts 3 to annularly plant brush materials on the periphery of the disk 1, providing an insertion hole 9 for a rotation shaft 8 at the center of the disk 1, and providing the peripheral portion of the insertion hole 9 with keys 10 or key seats 11 connected to the rotation shaft 8 by key connection, wherein adhesive pads 14 are interposed among the disks 1 of the disk brushes 7 and bonded to the surfaces of adjacent disks to form a monolithic structure of the same.
