1. A cavitation processing apparatus, comprising:
a tank configured to hold cavitation fluid therein;
a direction changing member disposed inside the tank and having a recessed shape;
a driving apparatus including a rotary shaft and a support member supporting an end of the rotary shaft, the driving apparatus and the support member being configured and arranged to support and rotate a workpiece disposed within the recess of the direction changing member; and
a nozzle configured and arranged to eject cavitation fluid toward the workpiece disposed within the recess of the direction changing member;
the direction changing member being configured to change a flow direction of the cavitation fluid that has collided with the workpiece disposed within the recess of the direction changing member, the direction changing member including
a side wall configured to change the flow direction of the cavitation fluid that has collided with the workpiece and that has branched off therefrom, and
a bottom portion configured to change the flow direction of the cavitation fluid that has collided with and been deflected by the side wall.
