摘要： A circuit connection apparatus has a connector including a housing in which a connection terminal is contained, a positioning guide portion provided therein at an opposite side to an opening portion of the housing, and a press-fit terminal extended from the connection terminal. Moreover, the circuit connection apparatus has a heat sink that includes a guide receipt portion fitted with the positioning guide portion—and an opening to be penetrated by the press-fit terminal and to which the housing is fixed. Furthermore, the circuit connection apparatus has a circuit board that includes a board positioning guide portion and a through-hole to which the press-fit terminal is pressure-bonded and that is fixed to the heat sink. Because the press-fit terminal and the through-hole can accurately be positioned, it is made possible that the reliability is raised and a simple assembly process suppresses the production cost from rising.

摘要： In an electric power steering device in which a control unit and a motor are integrated, when the control unit is housed in a case, although a frame, by which the motor and the control unit are compartmentalized, is required, there have been problems in that the case is deformed by a pressure which influences the case when the frame is provided, and a position accuracy of a shaft center of a rotation shaft of the motor is worsened. Therefore, in order to reduce a deformation of the case, a step portion is provided at an inner wall surface of the case and the frame is contacted to the step portion, and moreover, a connecting portion is provided between an outer circumference portion of the frame and an inner circumference portion of the case, whereby a movement of the frame is restrained.
