間が増える等の問題が生じる。On the other hand, the uniformity can be maintained by changing the connecting direction of the plurality of plate frames by 90 degrees between the case of arranging in the horizontal direction and the case of arranging in the vertical direction. However, in general, the outer shape of the functional surface of the wiring device often does not have rotational symmetry of 90 degrees, so that the decorative plate X has a shape such that the functional surface of the wiring device can be exposed when the wiring device is arranged in the lateral direction. If the opening window is formed, the outer shape of the opening and the functional surface do not match when arranged in the vertical direction, and it is necessary to separately prepare a makeup plate having an opening window corresponding to the vertical direction. Since a plurality of types of plates are prepared, the number of types of dies and the like increases, the manufacturing cost rises, and the trouble of inventory management increases.
