To provide a power device which can inhibit occurrence of noise and does not need maintenance.SOLUTION: A power device 1 includes: an electric motor 2; an inverter INV; a transmission 5; a differential gear 6; a case 4 which houses the electric motor 2, the transmission 5, and the differential gear 6; a left axel 3A in which one end part is connected to the differential gear 6 and the other end part extends from the case 4 to be connected with the left wheel WL; and a right axel 3B in which one end part is connected to the differential gear 6 and the other end part extends from the case 4 to be connected with the right wheel WR. A conductive part 70 having conductivity is provided between at least one of the left axel 3A and the right axle 3B and the case 4. The conductive part 70 includes: conductive grease 73; and an outer periphery side conductive member 74 which is provided in the conductive grease 73 and fixed to the case 4 and an inner periphery side conductive member 75 which is provided in the conductive grease 73 and fixed to the axle so as to face the outer periphery side conductive member 74 in a radial direction.SELECTED DRAWING: Figure 3

    【課題】メンテナンスが不要で、ノイズの発生を抑制可能な動力装置を提供する。【解決手段】動力装置1は、電動機2と、インバータINVと、変速機5と、差動装置6と、これら電動機2、変速機5及び差動装置6を収容するケース4と、一端部が差動装置6に接続され他端部がケース4から延出して左車輪WLに接続される左車軸3Aと、一端部が差動装置6に接続され他端部がケース4から延出して右車輪WRに接続される右車軸3Bと、を備える。左車軸3A及び右車軸3Bの少なくとも一方の車軸とケース4との間には、導電性を有する導電部70が設けられる。導電部70は、導電性グリース73と、導電性グリース73中に設けられ、ケース4に固定された外周側導電性部材74及び外周側導電性部材74に径方向で対向するように車軸に固定された内周側導電性部材75と、を備える。【選択図】図3
