Document Type and Number:
WIPO Patent Application WO/2018/011997
Kind Code:
A1
Abstract:
A wheel brush (1) comprises: an abrasive material bundle holder (3) including an annular abrasive material bundle holding surface (12) facing the outer circumferential side; and a plurality of abrasive material bundles (4) each formed of multiple strands of a linear abrasive material (5) bundled together. The abrasive material bundle holding surface (12) has a plurality of holding holes (16) arranged in the circumferential direction (R). The abrasive material bundles (4) protrude from the abrasive material bundle holding surface (12) toward the outer circumferential side while one end of each of the abrasive material bundles (4) is inserted in the corresponding holding hole (16). First protrusions (18) protruding toward the outer circumferential side are provided on respective first opening edge portions (17a) that are each adjacent, in a first direction (L1) of the rotation center axial direction orthogonal to the circumferential direction (R), to the corresponding holding hole (16) at an opening edge, of the holding hole (16), on the abrasive material bundle holding surface (12). The first protrusions (18) are continuous, in the circumferential direction (R), with each other to form a first flange portion (19).
