The utility model provides a power device which can restrain generation of noise without maintenance. The power device includes: a motor; an inverter; a variator; a differential device; a housing thataccommodates the motor, the variator, and the differential device; a left axle, one end of which is connected to the differential device and the other end of which extends from the housing and is connected to the left wheel; and a right axle, one end of which is connected to the differential device and the other end of which extends from the housing and is connected to the right wheel. A conductive portion having conductivity is provided between at least one of the left axle and the right axle and the housing. The conductive portion includes: conductive grease; and an outer-peripheral-side conductive member and an inner-peripheral-side conductive member provided in the conductive grease, the outer-peripheral-side conductive member being fixed to the housing, and the inner-peripheral-sideconductive member being fixed to the axle so as to face the outer-peripheral-side conductive member in the radial direction.
