However, in the conventional method described above, when the base plate is cut using a milling cutter, the rotational force of the milling cutter rotating in one direction acts directly on the louver, so a force in one direction is applied to the louver, causing the louver to deform. Therefore, the exterior design of the louver may not be as designed and may become unsightly.
