  • the power transmission device 1 has a speed change function, but the power transmission mechanism does not have a speed change function and simply decelerates (or may speed up). It's okay. If the power transmission device does not have a speed change function and is configured to decelerate the rotation of the motor and transmit it to the drive wheels WH, the oil OL for cooling the motor and the deceleration A hydraulic control circuit for supplying oil OL for lubricating the mechanism is arranged in the second chamber S2 together with the electric oil pump EOP. Further, in the above embodiment, the control unit of the power transmission device 1 is provided with the control valve CV, but the power transmission device 1 does not have a speed change mechanism, and the drive source is not the engine ENG. In the case of a motor (rotating electric machine), it may be a control unit including an inverter or the like that drives and controls the motor.
