PURPOSE: A polishing brush is provided to easily mount on a housing of a polishing device by forming coupling holes in a hexagonal shape and a rectangular shape in a first disk and a second disk mounted on both ends of a shaft. CONSTITUTION: A polishing brush comprises a cylindrical shaft(10), a mounting bar(20), and a slide protrusion(22) in a 'T' shape. A slide groove(12) in a 'T' shape is formed to the cylindrical surface of the cylindrical shaft in a longitudinal direction. A plurality of bristles(30a) is transplanted on the outer surface of the mounting bar. The slide protrusion in the 'T' shape is formed to the inner surface of the mounting bar in a longitudinal direction and is inserted into the slide groove by sliding.
