Abstract: A rolling bearing has an inner ring attached to a rotating shaft out of contact with a first end surface, and an outer ring is fitted onto an inner peripheral surface of a housing in contact with the first end surface. A sliding element is provided between a second end surface and the first end surface. A retaining portion is provided between the sliding element and the first end surface. A biasing portion is provided between the retaining portion and the first end surface to bias the retaining portion toward a second side in a lamination direction. The rotating shaft, the housing, the inner ring, the outer ring, a rolling element, the sliding element, the retaining portion, and the biasing portion are formed of a conductive material. The rotating shaft and the housing are electrically connected by the sliding element, the retaining portion, and the biasing portion.

Abstract: A core segment formed by laminating electrical steel sheets, a coupling hole having a lamination direction as its depth is formed in a portion of a yoke piece on a third side in a circumferential direction. An insulator includes a coupling pin protruding toward a second side in the lamination direction, at a portion of a first covering portion on a fourth side. A stator core formed by coupling core segments in a ring shape where the coupling pin of the insulator mounted on the core segment that is to the third side is inserted in the coupling hole of the core segment that is to the fourth side, and where a side surface on the fourth side of the yoke piece being to the third side and a side surface on the third side of the yoke piece being to the fourth side are in contact with each other.
