Although the example which made the wiring material 94a accommodated in the corner | angular part 452b of X2 side and the screw groove 453a of the terminal member 353 contact was shown, this invention is not limited to this. In this invention, what is necessary is just to comprise so that only one of the said electrical connections may be aimed at.

In the second embodiment, the terminal hole 352b is formed in a substantially regular octagonal shape, and the power wiring 94 is accommodated in the corner 452b formed on the inner surface of the terminal hole 352b. The present invention is not limited to this. For example, the terminal hole may be formed in a circular shape, and a plurality of groove-shaped recesses for accommodating the power supply wiring may be formed on the inner surface of the terminal hole. In this case, the inner surface of the terminal hole becomes a plurality of convex portions. Moreover, it is good also considering the some arc-shaped bottom part between several convex parts as several recessed parts by forming several convex parts in the inner surface of the circular hole part for terminals.

In the second embodiment, the wiring storage portion 353c is formed so as to extend in the X direction substantially orthogonal to the Z direction in which the shaft portion 353a extends. However, the present invention is not limited to this. In the present invention, the direction in which the wiring storage portion extends may not be the orthogonal direction as long as it intersects with the direction in which the shaft portion extends. In addition, by forming the wiring storage portion so as to extend in a direction intersecting other than the direction orthogonal to the direction in which the shaft portion extends, the wiring housing portion is formed to extend in a direction orthogonal to the direction in which the shaft portion extends. It is possible to increase the length of the wiring storage portion. Thereby, it is possible to contact the wiring and the inner surface of the wiring storage portion more reliably.
