By sticking sandpaper 56 to the vibrating plate 55, it is possible to perform chamfering of a substantially rounded corner of the C plane of the decorative plate. However, when the polishing machine 50 is used to chamfer the C-side corner of the decorative plate in a substantially R-shape, sandpaper 56 attached to the flat surface of the diaphragm 55 is used to make the decorative plate. Board C
It is possible that the corners of the face may be cut too flat.

Therefore, the object of the present invention is to reduce the working time by chamfering for rounding the corners where the surfaces of the members intersect, such as the corners of the C-face of the decorative plate, instead of manual work. Another object of the present invention is to provide a chamfering jig capable of shortening the length and making the substantially rounded portion uniform.
