Abstract: A cleaning brush includes bristles that have ends which come into contact with an object to be cleaned having irregularities on a surface thereof, and a brush base on which the bristles are arranged. The bristles include first bristles and second bristles. The first bristles have a thickness too great to reach bottoms of recessed portions of the irregularities on the surface of the object to be cleaned. The second bristles have a thickness small enough to reach the bottoms of the recessed portions of the irregularities on the surface of the object to be cleaned.

Abstract translation: 清洁刷包括具有与要清洁的物体接触的端部的刷毛，其表面上具有不规则性，刷毛基座布置在其上。 刷毛包括第一根刷毛和第二根刷毛。 第一刷毛的厚度太大，不能到达待清洁物体的表面上的凹凸部的凹陷部分的底部。 第二刷毛的厚度足够小以到达待清洁物体的表面上的凹凸部的凹陷部分的底部。
