Abstract

Provided is a brush capable of efficiently cleaning an inner corner portion and the like by converging bristles at high density without allowing bristle bundles to radially spread on a curved bristled surface.A bristled surface 4 of a cleaning brush 1 includes a narrow and smooth lower edge bristled surface 41 in a lateral direction, a narrow and smooth vertical edge bristled surface 42 that extends in an up-down direction and that forms an angle of substantially 90° with respect to the lower edge bristled surface 41, and a curved bristled surface 43 that connects the two bristled surfaces 41 and 42. The curved bristled surface 43 gradually increases in width from ends of the bristled surfaces 41 and 42. A large number of fixing holes 51 and 52 are formed in the lower edge bristled surface 41 and the vertical edge bristled surface 42 in rows in a length direction of the respective bristled surfaces. A greater number of fixing holes 53 in the width direction than in the lower edge bristled surface 41 and the vertical edge bristled surface 42 are formed in the curved bristled surface 43. The fixing holes 53 of the curved bristled surface 43 are formed to be inclined such that bristle tips of respective bristle bundles 63 implanted in the fixing holes 53 converge toward a circumferential center of a curve and a center in the width direction.
