PROBLEM TO BE SOLVED: To increase a degree of freedom in regulation of air jetting strength or a rotational speed of an air jetting port, so as to properly remove dust in compliance with a variety of a workpiece, an adhesion condition of dust, or the like. SOLUTION: In a rotary member 48 rotating to a supporting member 41, an air jetting member 65 provided with an air jetting port 68 is installed while posture regulation of the jetting member 65 is allowed. The air jetting direction from the air jetting port 68 can be regulated by changing the posture of the air jetting member 65. For example, a rotational speed of the air jetting port 68 is increased and jetting force is reduced, when the air jetting direction is brought close to the horizontal direction to a grinding face in a sanding belt. |
