PROBLEM TO BE SOLVED: To enhance cleaning performance of a cleaning brush provided in a machine tool for cleaning a surface on which a processing matter is loaded, prevent deterioration in quality of the processing matter, and enhance the cleaning performance, without making the cleaning brush rock. SOLUTION: There are provided a base 6, which rotates about an axial line 4 substantially perpendicular to a cleaning surface S; and a plurality of brush columns 50b arranged on an opposite surface to the cleaning surface S of this base 6. Each of the brush columns 50b is arranged along an inclined line 12, extending obliquely to a radial straight line 10, with the middle of the radial straight line 10 which extends around the axial line 4 as the starting point.
