To provide a motor unit which is integrally provided with an inverter and also allows size reduction.SOLUTION: A motor unit 10 comprises: a motor 1 which has a rotor rotatable around a motor axis and a stator; a transmission mechanism which transmits power of the motor and outputs it from an output shaft; a housing 6 which has a motor housing part for housing the motor and a gear housing part 63 for housing the transmission mechanism; an inverter unit 8 which supplies electric power to the motor; oil which circulates through an oil passage provided in the housing; and an oil cooler 97 which is provided on a path of the oil passage so as to cool the oil. Viewing from an axial direction of the motor axis, at least part of the inverter unit overlaps the oil cooler.SELECTED DRAWING: Figure 3

    【課題】インバータが一体化され小型化を図ることができるモータユニットを提供する。【解決手段】モータユニット10は、モータ軸を中心に回転可能なロータと、ステータとを有するモータ1と、モータの動力を伝達し出力シャフトから出力する伝達機構と、モータを収容するモータ収容部および伝達機構を収容するギヤ収容部63を有するハウジング6と、モータに電力を供給するインバータユニット8と、ハウジングに設けられた油路を循環するオイルと、油路の経路中に設けられオイルを冷却するオイルクーラ97と、を備える。モータ軸の軸方向から見て、インバータユニットの少なくとも一部は、オイルクーラに重なる。【選択図】図3
