An actuator control device supplies electrical power to a plurality of actuators via a plurality of controller units consecutively disposed and connected in one direction. A power supply unit or an input/output and power supply unit is interposed between each arbitrary number of controller units from within the plurality of controller units. In a case that the power supply unit is interposed, the power supply unit supplies electrical power to the block connected on a downstream side in a connecting direction. In a case that the input/output and power supply unit is interposed, the input/output and power supply unit performs input and output of signals to and from an exterior and the block that is connected on the downstream side in the connecting direction, while also supplying electrical power to the block.

A rotating electric machine unit includes a first and second rotating electric machine, a power control unit (PCU), a drive shaft, and a power transmission part. The first and second rotating electric machines have rotary shafts parallel to each other, and are disposed along a vehicle front-rear direction orthogonal to an axial direction of each rotary shaft. The PCU is disposed below the first and the second rotating electric machines in a vehicle up-down direction orthogonal to the axial direction of each rotary shaft. The drive shaft is disposed below the first rotating electric machine and behind the PCU. The power transmission part transmitting power between each rotary shaft and the drive shaft is disposed on the right side of each rotating electric machine and the PCU. A direction in which an outer shape of the PCU is longest is parallel to the vehicle front-rear direction.

An electric machine may include a housing having a front end and a back end where the front end is the primary mechanical coupling end. The electric machine may include a stator and a rotor arranged within the housing and a shaft connected to the rotor. The shaft may extend out of the front end of the housing and the shaft may be configured to be rotationally driven by the rotor or to rotationally drive the rotor. The electric machine may also include an electronic controller configured to control operations of the rotor and stator and the electronic controller may be mounted on the front end of the housing.

An actuator control device having a plurality of controller units connected to actuators, supplies electrical power to the plurality of actuators via the plurality of controller units. A connection confirmation unit confirms a connection state of the plurality of controller units, and a determination unit determines, based on a confirmation result of the connection confirmation unit, whether or not the connection state is in an allowable connection state in which supply of electrical power to the plurality of controller units is allowable.

A wide section 71d which contacts a connector member and positions the connector member relative to a connector housing part is provided in a section where a first securing part 71b of a cover member 70 is provided and is configured so as to be wider than the other parts of the section where the first securing part 71b of the cover member 70 is provided; hence, it is possible to use the wide section 71d in the pressing section (pressing point OP) of an extrusion pin. As a result, it is possible to suppress distortion of the cover member 70 and to sufficiently smooth the welded section (first securing part 71b) of the cover member 70 even when the shape of the cover member 70 is complicated.

A motor device is provided. A grommet member (80) is equipped with a pair of motor-side lip seals (82a1, 82a2) which elastically deform in the insertion direction of an external connector (CN) into a connector member (60), and are adhered to a connector cover part (71) (contact surface 70a) of the cover member (70); hence, it is possible to configure in a manner such that the mounting direction of the grommet member (80) onto a gear case (31), and the adhesion direction of the pair of motor-side lip seals (82a1, 82a2) to the cover member (70), or in other words, the direction in which sealing properties increase, are the same direction.

A first and second electric members respectively having electrical connection portions are electrically connected in a state that mutual positions are regulated by guide pins, and fastening screws which are inserted through fastening screw insertion holes of the second electric member are screwed into screw holes for fastening of the first electric member, and thereby the first and second electric members are fastened. At least one of the screw holes for fastening has large-diameter portions into which the guide pin is detachably inserted, and small-diameter portions equipped with female screw portions. The female screw portions are not arranged in the large-diameter portions, and inner diameters of the large-diameter portions are larger than root diameters of the female screw portions, and outer circumferential surfaces of the fastening screws which are screwed with the female screw portions and inner circumferential surfaces of the large-diameter portions are not in contact with each other.
