Effects of the Invention As described above, in the polishing apparatus of the present invention, a carrier floating prevention member is provided on at least one of the sun gear and the internal gear in a position above the carrier and does not prevent the polishing member from moving up and down. Since the polishing member is provided in a state protruding toward the space side, when the polishing member located in the space between the sun and internal gears is moved to a position above the space after polishing of the workpiece is completed. ,
During the upward movement of the polishing member, the carrier that has adhered to the bottom surface of the polishing member comes into contact with the floating prevention member at its peripheral edge and is peeled off from the polishing member, allowing it to be removed from both the sun and internal gears without coming off. Maintains meshing with gears. Therefore, the burden on the operator can be reduced by omitting the work of rearranging the carrier, and furthermore, it can contribute to automation of polishing processing.
