Summary:To enable suppressing the vibration of an inverter housing without deteriorating productivity.SOLUTION: A drive device includes: an inverter having an inverter housing in which a power conversion unit is stored; and a motor having a motor housing in which a rotor and a stator are housed. On the motor housing, a motor side stationary part which is a protrusion is formed. 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; an AC wiring connection part to which an AC wiring, which supplies power from the power conversion unit to the motor, is connected; an inverter-side coolant flow channel which contacts to the motor housing through a seal member and in which a cooling medium flows; and an inverter-side stationary part which is a protrusion contacting to a motor-side stationary part through an elastic body composed of a material of the same type as the seal member.SELECTED DRAWING: Figure 1 【課題】生産性を悪化させることなく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と、を備えた駆動装置であって、モータハウジングには、突起であるモータ側固定部が形成され、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、シール部材を介してモータハウジングに接触し内部を冷却媒体が流れるインバータ側冷媒流路、およびシール部材と同種の材料からなる弾性体を介してモータ側固定部と接する突起であるインバータ側固定部が形成される。【選択図】図1
