きる。Next, the operation of this embodiment will be described. With the surface of the base material 5 covered with the first and second coating materials 6 and 7, the opening 12 that crosses the groove 8 is gripped, for example. When the base material 5 is formed by press cutting in order to attach the like, notches 13 and 14 except a part of the protruding wall 9 are formed in the base material 5 at the portion corresponding to the peripheral edge of the opening 12 at the time of molding. Therefore, it is not necessary to cut the protruding wall 9 with a press-cutting blade, and a cutting stroke slightly larger than the wall thickness of the base material 5 is required. For this reason,
Compared to cutting the protruding wall 9, damage to the blade can be avoided as much as possible, and it is possible to avoid leaving an uncut portion in the portion of the protruding wall 9, thus increasing maintenance work due to damage to the blade. In addition, it is possible to prevent the addition of a post-process due to the uncut portion.
