To reduce burden on a driver in park lock operation, and avoid difficulty in realizing cost reduction and space saving due to installation of a drive source for park lock.SOLUTION: A motor drive unit 1 comprises a rotation preventing arm 86 movable between a position interposed between the teeth of a parking gear part 36 where the rotation of each gear in a transaxle 30 is prevented by preventing the rotation of a second gear 32, and a position not interposed between the teeth, and is mounted on a vehicle, wherein the motor drive unit comprises a transmission mechanism 70 that transmits the driving force of a motor shaft of an electric pump 60 for transferring oil in a housing 40 of the transaxle 30 to the rotation preventing arm 86.SELECTED DRAWING: Figure 1

    【課題】パークロック操作時の運転手の手間を軽減し、且つパークロックのための駆動源の付設に起因して低コスト化、及び省スペース化を困難にしてしまうことを抑える。【解決手段】パーキングギヤ部36の歯間に介在して第2ギヤ32の回転を阻止することでトランスアクスル30内の各ギヤの回転を阻止する位置と、前記歯間に介在しない位置との間を移動可能な回転阻止アーム86を備え、車両に搭載されるモータ駆動ユニット1であって、トランスアクスル30のハウジング40内のオイルを移送するための電動ポンプ60のモータ軸の駆動力を回転阻止アーム86に伝達する伝達機構70を備える。【選択図】図1
