To enable suppressing the vibration of an inverter housing.SOLUTION: A drive device includes: an inverter device having an inverter housing in which a power conversion unit is stored; and a motor device having a motor housing in which a rotor and a stator are housed. On one surface of the inverter housing, there are formed a plurality of stationary parts which mechanically fix the motor housing and the inverter housing, and an AC wiring connection part to which an AC wiring, which supplies power from the power conversion unit to the motor device, is connected. The AC wiring connection part is formed on one side of the one inverter housing surface than the center of the stationary part, which is the center of a region surrounded by the plurality of stationary parts. On the other side than the center of the stationary parts, a salient contacting to the motor housing is provided.SELECTED DRAWING: Figure 1 【課題】インバータのハウジングの振動を抑制できる。【解決手段】駆動装置は、電力変換ユニットが収納されるインバータハウジングを有するインバータ装置と、ロータおよびステータが収容されるモータハウジングを有するモータ装置と、を備え、インバータハウジングの一面には、モータハウジングとインバータハウジングとを機械的に固定する複数の固定部、および電力変換ユニットからモータ装置に電力を供給する交流配線が接続される交流配線接続部が形成され、インバータハウジングの一面のうち、複数の固定部で囲まれる領域の中心である固定部中心よりも一方側には、交流配線接続部が形成され、固定部中心よりも他方側には、モータハウジングと接する凸部が設けられる。【選択図】図１
