Abstract
A wheel brush () includes a grinding element bundle holder () having an annular grinding element bundle-holding surface () that faces the outer circumferential side and a plurality of grinding element bundles () that are formed by gathering a plurality of wire-shaped grinding elements (). The grinding element bundle-holding surface () has a plurality of holding holes () arrayed in a circumferential direction (R), the grinding element bundles () protrude to the outer circumferential side from the grinding element bundle-holding surface () while one end portions are inserted into the holding holes (). First protrusions () protruding to the outer circumferential direction are provided on first opening edge portions () adjacent to the holding holesat a first direction (L) side in the rotational center line direction orthogonal to the circumferential direction R (R) in opening edges of the holding holes () in the grinding element bundle-holding surface (). The first protrusions () are continuous in the circumferential direction R (R) to configure an annular first flange portion ().
