By rotating in the circumferential direction with respect to 4, the mounting position can be adjusted to an arbitrary position in the horizontal direction in a state where each connecting fitting 10c is mounted on the second connecting member 15.
Also, since the second connecting member 15 has a degree of freedom in the circumferential direction with respect to the first connecting member 14, the connecting fittings 1 generated when the electric wires 22 connected to the connecting fittings 10c are extended and relaxed.
0b can be reduced.
