摘要： In a control unit including a press-fit terminal, a substrate includes: a connected portion into which the press-fit terminal is connected; and a guide member, which surrounds a periphery of the connected portion and extends from the substrate. The press-fit terminal includes: a connecting portion formed on a tip end side of the press-fit terminal; and an enlarged portion formed adjacent to the connecting portion. The guide member includes: an opening portion, which opens in a direction in which the press-fit terminal is positioned; a guide hole extending from the opening portion to the substrate; and a reduced-hole portion formed adjacent to the opening portion. The guide hole is configured such that, when the connecting portion of the press-fit terminal is connected to the connected portion of the substrate, the enlarged portion of the press-fit terminal closes the reduced-hole portion of the guide hole.

摘要： Provided is an electric driving device including a first protruding portion protruding from a holder surface. A plate-like portion has an opposed surface opposed to the holder surface. A first through hole in the plate-like portion is defined by a first through hole forming portion formed in a cylindrical shape so as to project from the plate-like portion to a side opposite to the opposed surface. The first through hole has an inner surface including a first hole inclined inner surface and a first hole cylindrical inner surface extending from the first hole inclined inner surface to the end portion of the first through hole forming portion. The first protruding portion is press-fitted into the first through hole under a state in which a plurality of first ribs are in contact with the first hole cylindrical inner surface.

摘要： In an electric rotating machine apparatus according to the present disclosure, noise-removal capability is secured by adopting a structure in which an external terminal is connected with a protruding portion, of a control circuit board in a control unit, that protrudes from a through hole of an electromagnetic shield and in which a filter unit is provided. Because a conventional dedicated wiring board for mounting the filter unit thereon is not required, the foregoing structure can contribute to downsizing and cost reduction. In addition, the foregoing structure can contribute to downsizing and cost reduction of an electric power steering apparatus equipped with the electric rotating machine apparatus according to the present disclosure.
