A communication hole 12 is formed for communicating the upper part of the hole 5 and the dummy through hole 11. The dummy through-hole 11 and the communication hole 12 are formed because there is a member that interferes with the other side of the through-hole 5 and there is no gap for inserting the connector 7 into the through-hole 5, but the flat cable 6 is wired. This is because the flat cable 6 can be wired to the through hole 5 when only a gap exists. The through-hole 5 is small as long as the flat cable 6 can be inserted, and the dummy through-hole 11 is set slightly larger than the outer shape of the connector 7 so that the connector 7 can be inserted.
[0018]
The flat cable 6 is wired in the following procedure. If the part formed between the through-hole 5 and the dummy through-hole 11 by forming the communication hole 12 as shown in FIG. 1 is defined as the partition part 13, as shown in FIG. Is bent to form a bent portion 6 a, and the bent portion 6 a is inserted from the communication hole 12 to the other side of the partition portion 13. Then, the state shown in FIG. Thereafter, the connector 7 is inserted into the dummy through hole 11 as shown in FIG. Then, as shown in FIG. 3C, the flat cable 6 is separated from the dummy through hole 11 and is inserted only into the through hole 5. In the state where the flat cable 6 is inserted only through the through hole 5 as described above, the counter plate 4 is coupled to the housing 2 via screws or the like as shown in FIG. Then, the portion of the dummy through hole 11 is closed by the presence of the housing 2 as shown in the perspective view of FIG. That is, substantially the same state as that in which the small through hole 5 is formed and the flat cable 6 is inserted is realized. Moreover, as shown in FIG. 3D, the flat cable 6 can be wired without any problem even when the structure 8 is present on the back side of the counter plate 4 and interferes.
