PROBLEM TO BE SOLVED: To supply a lubricant to a gear of a reduction gear, in a two-motor vehicle drive unit having a parking lock mechanism.SOLUTION: A reduction gear is composed of: an input gear shaft 23 having an input gear 23a to which power is transmitted from a motor shaft; an output gear shaft 25 having an output gear 25a for transmitting drive forces to wheels; and an intermediate gear shaft 24 which is arranged between the input gear shaft 23 and the output gear shaft 25, and has a large-diameter gear 24a which is geared with the input gear 23a, and a small-diameter gear 24b which is geared with the output gear 25a. A parking lock mechanism 40 has a parking gear 41 which is arranged at the input gear shaft 23 on an extension line in a radial direction of the small-diameter gear 24b of the intermediate gear shaft 24 in a reduction gear casing 20, and a parking pole 42 having a claw part which can be engaged with and released from the parking gear 41. An outside diameter of the parking gear 41 is formed larger than an outside diameter of the input gear 23a, and a part of the parking gear 41 is immersed into a lubricant which is sealed into the reduction gear casing 20.SELECTED DRAWING: Figure 4

    【課題】 パーキングロック機構を備えた2モータ車両駆動装置において、減速機の歯車に潤滑油を供給することを課題とする。【解決手段】 減速機は、モータ軸から動力が伝達される入力歯車23aを有する入力歯車軸23と、駆動輪に駆動力を伝達する出力歯車25aを有する出力歯車軸25と、入力歯車軸23と出力歯車軸25との間に設けられ出力歯車23aと噛み合う大径歯車24aと出力歯車25aと噛み合う小径歯車24bを有する中間歯車軸24と、からなり、パーキングロック機構40は、減速機ケーシング20内の中間歯車軸24の小径歯車24bの径方向の延長線上の入力歯車軸23に設けられるパーキングギヤ41と、パーキングギヤ41に係脱可能な爪部を有するパーキングポール42とを有し、パーキングギヤ41の外径は、入力歯車23aの外径より大きく形成し、パーキングギヤ41の一部が減速機ケーシング20に封入した潤滑油に浸かるようにした。【選択図】 図4
