整作業を容易に行うことができる。As described above, according to the present invention, the second polishing jig is inclined when the angle between the rotation axis of the second polishing jig and the swing member is changed. Since the deviation between the swing center of the first polishing jig and the center position of the second polishing jig can be eliminated by adjusting the position of the second polishing jig while maintaining the angle by the position adjusting means, There is no need to adjust a swinging member that generates a complicated movement, and the adjustment operation can be easily performed.
