A drive unit includes an internal combustion engine () disposed in an engine compartment (), a first electric motor () and a second electric motor (), and an inverter () disposed above an electromotive unit (). The drive unit has: a first harness () that connects the inverter and the first electric motor; a second harness () that connects the inverter and the second electric motor; a step portion () formed so as to be recessed on one side or the other side, in the left-right direction, of the upper end of the inverter; and an AC terminal block () disposed in the step portion. The first harness and the second harness respectively extend downward from the DC terminal block while extending outward, and are respectively connected to upper parts of the first electric motor and the second electric motor.

Vehicle drive unit

A vehicle drive unit includes an internal combustion engine (), an electromotive unit () having a first electric motor () and a second electric motor (), an inverter () disposed above the electromotive unit, a first harness () that electrically connects the inverter and a first terminal block () of the first electric motor, and a second harness () that electrically connects the inverter and a second terminal block () of the second electric motor. The first electric motor and the second electric motor are disposed in a vehicle front-rear direction. Of the first electric motor and the second electric motor, one electric motor is disposed on the front side in the front-rear direction, and the other electric motor is disposed on the rear side in the front-rear direction. The other electric motor is offset upward in the up-down direction with respect to the one electric motor. The electromotive unit has a predetermined space (A) formed: in a region above the one electric motor and in rear of the front end of the one electric motor; and in a region in front of the other motor and below the upper end of the other electric motor. The first terminal block and the second terminal block are located in the predetermined space.

To reduce the number of components, size and weight while preventing breakage of the casing, a high-voltage device provided adjacent to a vehicle component constituting a vehicle includes: a casing housing a high-voltage portion; and a plurality of bolts fastening the casing to an attachment portion to which the casing is attached. The high-voltage device has a first end face at which the casing is in contact with the attachment portion and a second end face opposite to the first end face, and the plurality of bolts are composed of long bolts extending from the second end face to the first end face. The long bolts are each attached to the casing at a position between the vehicle component and the high-voltage portion.
