To provide an electric driving device and an electric power steering device that have a smaller size in the axial direction and suppress stress on a circuit board due to electrical connection between a motor and the circuit board if a terminal block is provided. An electric driving device includes a motor and an electronic control unit that controls rotation of the motor. The electronic control unit includes a first circuit board, a first heat sink, a second heat sink, and a terminal block. The second heat sink sandwiches the first circuit board between it and the first heat sink. The terminal block is fixed to the side surface of the second heat sink and electrically connects motor coil wiring to the first circuit board.

A steering system according to an embodiment may include a steering assistance device configured to assist a steering device positioned between a steering wheel and a wheel, and a noise reduction device configured to reduce noise of the steering system with the steering assistance device.

A semiconductor device is provided that allows an IC chip and a heat sink to be prevented from being short-circuited even if facing surfaces of the IC chip and the heat sink are located closest to each other due to manufacturing variations and other variations. A controller for a motor apparatus includes a substrate on which MOSFETs are mounted and a heat sink provided facing the substrate and the MOSFETs so as to dissipate heat generated by the MOSFETs. Insulating portions are each provided on a facing surface of each MOSFETs. Protruding portions are each provided on a facing surface of the heat sink so as to protrude from the heat sink toward the insulating portion of the corresponding MOSFET. A second clearance smaller than the first clearance is formed between each of the insulating portions and the corresponding protruding portion.

An electric drive device and an electric power steering device are provided that reduce the size of a motor in an axial direction parallel to a shaft and in a radial direction of the shaft. The electric drive device includes a bus bar module in which a connector, a first power supply terminal, a second power supply terminal, positive electrode bus bar wiring that electrically connects the connector to the first power supply terminal, and negative electrode bus bar wiring that electrically connects the connector to the second power supply terminal are integrally formed with the connector. The positive electrode bus bar wiring and the negative electrode bus bar wiring extend from the connector, bypass an extended line of the shaft, and are electrically connected to the circuit board in positions at distances from the connector larger than a distance from the connector to the extended line of the shaft.

An embodiment provides a sensing apparatus comprising: a first rotation part; a second rotation part in which the first rotation part is disposed; a housing in which the second rotation part is disposed; and a first metal member disposed between the housing and the second rotation part, wherein the second rotation part includes a first holder and a second holder combined with the first holder, and the first metal member includes a body disposed between the first holder and the housing and a first flange portion extending radially outward from the body.
