Abstract
A rivet is applied from a rear surface of a fabric for mounting a burr on a front surface of the fabric. The rivet comprises a disk-shaped base, and a shank projecting from and concentrically with the base. The base includes an annular recess around a proximal end of the shank, which is depressed in a direction opposite to the shank-projecting direction, and a flange radially outward from the recess. The flange includes a plurality of bumps which are raised from an upper surface in the shank-projecting direction. The bumps may be provided on the upper surface of the flange at equal circumferential intervals, and a top of each of the bumps may be a curved face. The recess may have an inclined outer surface adjacent to the flange. Each of the bumps may have an inclined inner surface extending continuously from the inclined outer surface of the recess.
