As shown in
In the example shown in the drawings, the distal ends of the six lead wires u1n, v1n, w1n, u2n, v2n, w2n led out to the exterior through the through-holes in the wire cover 8a are directly connected to terminal sections t1 to t6 of a circuit board 21 provided within the electrical unit 20, and the distal ends of the three lead wires u1, v1, w1 led out through the through-holes 800 in the wire cover 8b are directly connected to terminal sections tu, tv, tw provided to the circuit board 21. In addition, lead wires u2, v2, w2 led out through the through-holes in the wire cover 8c are directly connected to prescribed terminal sections provided to the circuit board 21 (although this relationship is not shown in the drawings).
