Abstract: A wire harness includes a tubular member, an electric wire member, a cover member, and a holder. The electric wire member includes electric wires connected to each other. The electric wires each have a core wire covered by an insulation sheath. The cover member covers a circumference of a connected part of the electric wires. The electric wire member is inserted through the tubular member. The holder is tubular and is arranged at an end part of the tubular member to protect the electric wire member at a part where the cover member is arranged. The electric wire member includes a double-insulation portion where the core wire is covered by the insulation sheath and the cover member. The holder includes a hollow portion in a part where the double-insulation portion is located.

Abstract: To provide a wire harness that restricts rotation of a wire in a holder, a wire harness includes a tubular member, a wire member extending through the tubular member, and a tubular holder holding the wire member in the tubular member. The holder includes a first segment and a second segment, which are separated by a separation plane extending in a longitudinal direction of the holder. The first segment includes a holding portion that holds the wire member in the holder. Also, the second segment includes a holding portion that holds the wire member in the holder.

Abstract: The terminal structure includes an electric wire including a core wire and a terminal member attached to the electric wire. The terminal member includes a joining portion to which the core wire is joined and the sealing portion surrounding the joining portion and including an opening portion having the joining portion exposed therethrough. The core wire is joined to the joining portion through the opening portion and is in close contact with the sealing portion annularly around the opening portion.

Abstract: A wire harness includes a first electric wire member including a first flexible wire and a hard wire electrically connected to the first flexible wire, a second electric wire member including a second flexible wire, and a tubular member through which the first and second electric wire members extend. The wire harness also includes a tubular holder that is attached to a longitudinal end portion of the tubular member and holds the first and second electric wire members therein. The holder has a first housing recess that is located in an inner surface of the holder and houses the second electric wire member.

Abstract: A motor controller, an electric power steering device using the motor controller, and a vehicle using the motor controller are provided. The motor controller includes plural hardware sets configured to operate in a normal state and to output a motor current, a control operation device configured to control the plurality of hardware sets commonly, an electric motor configured to operate with motor current output from each of the plurality of hardware sets, and an abnormality diagnosis unit configured to diagnose an abnormality of each of the plurality of hardware sets. In the control device, when there is an abnormal hardware set that has been diagnosed by the abnormality diagnosis unit, the control operation device stops an operation of the abnormal hardware set that has been diagnosed, and continues driving of the electric motor with a normal hardware set.

Abstract: An electronic control unit (50) includes power modules (60A), (60B), an input and output board (70) on which an input connector (71) and an output connector (72) are mounted, and a control board (80). The input and output board (70) and the control board (80) are arranged to vertically face each other. A discrete part (73) that is taller in height (H1), (H2), (H3) than a half (D/2) a distance (D) between the input and output board (70) and the control board (80) is mounted only on a face (70e), of the input and output board (70), facing the control board (80).

Abstract: An electronic controlling unit includes a housing configured to accommodate a power module, an input/output board, and a control board. The housing includes a mounting portion and a ceiling portion opposed to each other with a spacing therebetween in one direction, and four side wall portions located between the mounting portion and the ceiling portion. At least one of the at least four side wall portions is an inclined side wall portion inclined inwardly at an acute angle with respect to the mounting portion.

Abstract: An electronic control unit, an electric power steering device, and a vehicle are provided, such that the power loss from output terminals of two power modules including first and second power modules to the electric current joining point is suppressed. The electronic control unit includes an input and output board connected with the first and second power modules. First and second conductor patterns respectively connected with output terminals of the first and second power modules and extending independently of each other are formed in the input and output board. A terminal is mounted on the output connector, the terminal including first and second board connection portions respectively connected with the first and second conductor patterns.
