Abstract: An electronic control apparatus comprises a housing of synthetic resin, a cover of metallic material, fixed to the housing by a fastening bolt, and an electronic control section enclosed in an interspace formed between the housing and the cover. A conductive gasket is interposed between a joint surface of the housing and a joint surface of the cover, and arranged to ground the cover electrically through the conductive gasket, to relieve static electricity from the metallic cover to a ground or a main body of a vehicle.

Abstract: It is an object of the present invention to provide an axial gap type motor in which continuously wound coils can be easily assembled as a stator coil of the axial gap type motor, and the workability for the work of winding wires without any connecting wire on a gap surface can be improved. The axial gap type motor includes a stator and a rotator facing each other in a rotation shaft direction, and the stator is arranged with a plurality of cores and a plurality of winding wire coils wound around the cores arranged in a circumferential direction. First, second, and third winding wire coils are wound, with a single continuous conducting wire, around first, second, and third cores arranged in order adjacent to each other in the circumferential direction. A winding direction of the second winding wire coil wound around the second core located in a center and winding directions of the first and third winding wire coils wound around the first and third cores both being located adjacent to the second core are a negative direction.

Abstract: Disclosed is an electric fluid pump wherein a radial outer circumferential surface of a stator and an insulating flat surface of an insulating base part, on which crossover wire guides are mounted and which is perpendicular to the outer circumferential surface of the stator, are covered with a synthetic resin coating of predetermined thickness. Since the insulating flat surface of the insulating base part on which the crossover wire guides are mounted and the outer circumferential surface of the stator are covered with the synthetic resin coating, it is possible that, even when a winding force is exerted in a radially inward direction of the stator by winding of crossover wires on the crossover wire guides, the synthetic resin coating on the outer circumferential surface of the stator suppresses changes in the mounting angles of the crossover wire guides and thereby prevents loosening of the crossover wires.
